Hi guys my first post here

I am in the process of my first build, and I have 2 options I can take and I just wanted to know from some more experienced pc builders which would be the better option

My first option is:

case: nzxt phantom

heatsink: noctua nh d14

PSU: hx 750

GPU: xfx 6950

Motherbaord: MSI gd55

Cpu: i7 2600k

Ram: 4gb 2000mhz mushkin blakcline

HDD: 1tb samsung f3 spinpoint

My second option is the same but replacing the 2600k with a i5 2500k and having xfx 6850s in crossfire, my budget is about 1100 pounds, any suggestions are welcome!

Looks like you have been paying attention to other reccommendations all good choices, though im sure you could just got for the i7 2500k and oc it just as you have suggested and go for 6950s in xfire

I have a 6850, and it's awesome, but I don't think it's ever advisable to build a new rig with a two-GPU setup. (With the possible exception of two of the very highest-end cards.) Price follows performance very closely, so buy the best single GPU you can currently afford: you'll get the same bang for buck and you'll have room to grow.

Thanks for the quick replies, ive read some reviews and people are suggesting that there is only 3% difference between 2600k and 2500k, is this true?

surely it depends on the applications being used. the 2600k has 8threads/4cores, the 2500k has 4threads/4cores. i think that is the major difference

i7-2600K

i5-2500K

EDIT: This is good for comparing them side by side:

Comparison

major differences:

thread number/hyperthreading

diff. default/turbo clock speeds (by 0.1GHz)

i7-2600K has 2MB more cache

higher bus/core ratio (not sure about what this means performance wise)

Fact is for gaming you probably won't need all 8 threads, and when it comes to performance it pays to save a bit on the CPU to get better graphics, so I would opt for the i5 2500K with crossfire 6950s, but I'm a gamer and that's what I need my computer to do.

I think you guys have misunderstood, my second option is crossfire 6850s, 6950s would be an upgrade later on.

If i follow Eunoias advice, i could afford a gtx 570 if i were to buy a single gpu system, but it is 80 pounds more and if i unlock my 6950 to a 6970 i am not sure that the performance difference is worth it.

there's no guarantee that unlocking a 6950 to a 6970 will be stable as there is as much power gettin to the card unlike with proper card so it might end up being a total fluke if you get one that does

So would you suggest a 6950 or 6850 crossfire if i dont unlock the card and just overclock it?

there will be plenty of power as long as you get a good quality psu

the two extra pins on the 6970 are simply grounds for added stability and therefore as long as your psu cables are good quality your 6 pin cables should have no trouble coping with the extra power
