i7 3930K or I7 3820

[micketkeong]

Hi, I wanted to upgrade my current PC to X79, can I know whether to choose i7 3930K or i7 3820? Motherboard is ASUS Rampage 4 Extreme.

I also would like to know will the i7 3930K or i7 3820 bottleneck my 2 GTX 590 in quad sli?

Thanks

Dude if your gonna go x79 esp with the rIVe get the K hands down even stock clock its a beast and you will be far from disappointed. Unless your mobo is tempremental like mine lol which is why i know stock clock is a beast

 

[dipzy]

3930k would be the one to get, its just crazily fast

 

[yassarikhan786]

Neither will bottleneck your graphics cards and out of the two I would get the 3930K hands down.

 

[PetrolHead247]

3930K for sure, it's the best 2011 socket CPU imo

 

[Vicey]

3930K is the only processor worth buying on LGA 2011 in my opinion.

If the ivy bridge E coming out, it still can support LGA 2011 right? I would like to save on the i7 3820 for upgrade to ivy bridge E, my main concern is my current i7 920 seem like bottlenecking my GTX 590 Quad sli, just don't want to have bottleneck...

The plan so far is that IB-E is going to support the current 2011 socket. But tbh. with the Ivy Bridge coming now to wipe out the Sandy's and the news about Haswell coming next year about the same time as IB-E I wouldn't be surprised to see them just drop the whole thing. Although this is just speculation and by no means do I proclaim to be correct. Neither has Intel said anything about it.

If you are willing to pay the price and are going to use your PC for more than gaming, then I'd say feel free to go for the 2011 with the i7 3930K. The 3820 is a pretty good and "cheep" processor, but if money is an issue I wouldn't go for 2011 in the first place. Besides the 2600K overclocked performs (I'd say) almost as good as the 3820, plus it's a more tricky CPU to OC then the 2600K since it requires you to do it the "old" way.

Besides man, two 590? I find that to be overkill even if it's last gen.

I reckon that if you go for a 2011 with the K-model you can run that rig for at least 3 years solid.

This is valid thinking, you can save money now by buying the cheapest 2011 CPU, which will net you the same performance as a 2600/2700K, the only differances is the 1155 will be easier to overclock because they are unlocked.

The problem with 1155 boards will be your 2 590s will be choked down to 8x each, the 2011 boards will give them 16x each

With Ivy Bridge coming out people buying all new gear can buy Z77 MB an IB CPUs and throw in a set of 7970s, or 680s,(which run very close and sometimes beats the 590) and run everthing at PCI-e 3.0, the 8x per graphics card wont be much of a problem, but I'm not sure how much your 590s will gain in this setup, because they are PCI-e 2.0, just gotta wait a few more weeks until 1155 IB is out and see how older cards respond to this setup by reading reviews.

Sandy Bridge-E can provide full 16x PCI-e 2.0 to your 590s right now, by the time they release IB-E(and if we don't need new motherboards) the 2.0 PCI-e of your 590s will become the bottleneck.

3820 and the 3930K will both overclock about the same(with the 3930K being alittle easier because it's unlocked) but you will have 50% more performance because it has 6 cores(12 threads)

Depending on the games you play the 3930K may be a waste of money(if the game can't use that many cores/threads) but for everyday computing it will be a monster(50% faster than the 3820, in programes that can use the extra cores and threads, total waste in those that can't)

You have to look at what your trying to get out of the system? If all you want to do is run Crysis 2 on a 1080p 120Hz monitor, the 3820 will be just fine. If you want to Metro on 3- 2560x1600 monitors your better off being happy with what you have, while waiting on next gen stuff.

point is, we need to know what you want from your next computer? give us alittle more info.....

i wanted to get a 590 to start with but i had to pay 800 euros and they don't make em anymore

get a 680 instead m8 cheaper and better for ur 2011 setup

 

[micketkeong]

hi, I will keep my GTX 590 quad sli for a few year until newer technology or more demanding game come out, every game I play now got no issues and all can be play at max setting with 60 FPS v-sync (don't like the tearing), just I keep on think the bottleneck thing when gaming. is it ok If I go with the i7 990X?

 

[Vicey]

Keep in mind that most of the rumours and leaked Intel slides (and that is all we really have at the moment) are showing LGA 2011 Ivy Bridge processors to be released in 2013. Possibly Q2. That is around 12 months from today.

I just wanted to mention that because you said above you're thinking about getting a 3820 and wait for Ivy Bridge. That's a long wait and I just wanted to make you aware of that.

Ivy Bridge on LGA 1155 will be here a lot sooner, possibly at the end of this month or early next month. That's a big difference between the two sockets in the time scale that they will receive Ivy Bridge processors and obviously the Ivy Bridge processors on 1155 will be faster than a 3820 as already shown in leaked benchmarks performed on Engineering Samples.

I think the only game I've seen bottlenecked by a CPU is Empire/Napoleon/Shogun II Total War games. You will be fine with a 3930k plus that has greater longevity with good OC potential.

 

[micketkeong]

hi all, I will get i7 3930K & Asus Rampage 4 Extreme 2moro, thanks for all the suggestions, but for the RAM, is it ok if I take Corsair CMZ16GX3M4X1866C9R?

 

[TheOsTech]

[sup]NOOOOOO. If all you care about is gaming performance with just two cards, a z77 and ivy would be good and much cheaper. to be honest I doubt your 920 is bottlenecking your cards in the least. it may be that you motherboard has a multiplexing chip to support 3-4 graphics cards and that has been shown to impead some proformance or you may perceive things like microstuddering as performance issues. Also keep in mind that quad sli has always been poorly supported. [/sup]

[sup]There may be some benefit for you in the 2011 socket and a quad core with quad channel memory, no multiplexing chip and twice the pci-e bandwidth but even then it wont be night and day. the 4 core will be almost identical gaming experience as the six at about 1/3 the price. I would bet real money no human alive could tell the difference without some serious data nitpicking. they just don't optimize games for more then 4 cores so its all about the fastest four cores you can have. Also, a quick ssd would improve gaming. if you have unlimited funds why not just buy the most expensive parts every six months or year? if you have a limit put you money into what will improve your experience the most.[/sup]

[sup]in short I recommend you get this[/sup]

[sup]listed in order of importance[/sup]

[sup]the best 2011 mb you can afford and the quad core.[/sup]

[sup]an ssd[/sup]

[sup]save your money up and buy 2 690's when you can and sell your 590's. [/sup]

[sup]surround sound and 65 inch oled tv for a monitor.[/sup][sup] [/sup]

[sup]coming in dead last and only if you must a six core 2011 cpu for bragging rights [/sup]

 

[TheOsTech]

one or two more things. For the best gaming experience I recommend installing fraps to check your frame rate. in the NVidia driver, set the following under 3d settings.

ambient occlusion quality

aa gamma correction on

power management mode maximum performance

anisotropic sample optimization off

negative lod bais clamp

texture filtering quality high quality

trilinner optimizations off

triple buffering on

vertical sync force on

this will make your cards work harder but will make your games look their best

also

go into your bios and turn off speed step and all other power management things that dynamically down clock your cpu as they can affect frame rate. you can verify you cpu is not throttling by installing cpu-z and checking the speed at idle. would not hurt to check you cpu temps while gaming with core temp as well.

last go into your game of choice and turn off in game v sync.

if your frame rate never goes bellow 60 then you are doing very well. if it doesn't seem smooth as butter at 60 then you are having microstuddering issues that can be resolved by going to a single 680. if you frame rate drops whenever your hard drive light comes on a bunch or stays solid you need more memory and/or an ssd.

best of luck to you.

Reading your replies OsTech the only thing that comes to mind is this:

No offence to you but I think your advice is not very good.

 

[TheOsTech]

Vicey, If you disagree please elaborate on what. Vague statements really aren't going to help him make an informed decision. Obviously you seem to think my opinion is laughable so back that up with a counter opinion of your own so we can debate it. otherwise its just another pointless troll.

 

[pickyantivirus]

The 3930k eats the competition alive! It will even match a 3960X in most tests. In short it's the muts nuts.

EDIT: The 3820 is more comparable to a i7 2700k to be fair.

Ivy Bridge? - It's nothing but a die shrink unless you meant Haswell. Haswell is the next big performance increase and after reading your frankly arsey comment saying everyone else was wrong it's interesting you think IB is so much faster and that the IB version of other SB chips will be much better, which is in fact not the case.
