What to do

[Madmullen]

This is my current spec:
Case:Corsair Osbidian 750D
Motherboard:Asrock 990FX Extreme4
CPU: Amd FX(tm)6300 six core Black Edition 3.5Mhz (not clocked yet)
Ram:Corsair Vengence 16GB Dual Channel @ 1600MHZ
Graphics: 2 X Asus Gefore GTX660 1020MHZ 2GB PCI Express 3.0 HDMI Direct CU II OC runing in SLI (not clocked yet)
Sound: Onbrd
HDD: Baracuda 1TB
HDD: Toshiba 250GB
DVD: LG Lightscribe
PSU: Corsiar RM Series 650W
Aerocool X-Vision 5 Channel LCD Fan Controller

Cooling: Corsair Hydro H105 running in Push
Corsair 2XSP120mm
1 x SP120mm Exhaust
2 x SP140mm Intake

but due to faulty Graphics cards they are being sent back for a refund.

Now I also have the following:

ASRock FM2A75 Pro4 AMD A75 Chipset (Socket FM2) DDR3 ATX motherboard

AMD A8-5600K Black Edition 3.60GHz (Socket FM2)APU Trinity Quad Core Processor
spec:Specification:-
- 4 cores (Quad Core technology)
- 3.60GHz Stock speed
- 3.90GHz Turbo speed
- 4MB Cache
- Multiplier Unlocked (Great for overclocking)
- 100W TDP
- Onboard IGP: HD 7560D, 760MHz Core speed, 256 Stream Processors
- Hybrid Crossfire Capable with HD 6670

The ? is do I change to the above brd and chip and get the relevent graphics card to go with it or keep the orginal setup and just buy new cards or a single.

I have always used Nvidia based cards but AMD based Boards and chips run better with Radeon based cards so I stuck what to do.
Refunds due in about 10days MAX spend £300 butless would be better.

So as you see need a bit of help

Keep your old rig and get a new GPU. A 280x should be in your budget.

The A8 isn't as powerful as the 6300. Don't downgrade

was thinking either
MSI Radeon R9 270 with 4g onbrd £180 or
2 X MSI Radeon R9 270 with 2g onbrd £138 x 2 = £276 CrossFire now they run at 180w would the RM650 psu be ok

Crossfire doesn't double the amount of memory - With two GPUs with 2GB each you would still only be able to use 2GB in total.

Also, are you sure that your GTX 660s were actually faulty? I mean the overheating could have happened due to software problems after all. Two faulty GPUs at the same time is extremely unlikely.

MSI do have a 4GB 270x... So yes the memory is double and will still be 4GB if put in Xfire. Now for the regular 2GB card you are correct.

Yes, what else would I mean? 2x 2GB in crossfire means you can still only use 2GB in total.
If you get one 4GB card of course you have a card with 4GB.

There might be problems with memory bandwith and memory bus which could bottleneck the card and I'm not quite sure if a 256Bit bus and 170GBPs is enough to utilize 4GB VRAM.

There was something wrong with them I had already contacted Asus support regarding the overheating and Dabs have kindly said they will refund me as these cards have been discontinued.
I could go for a R9 280 but not sure its worth the extra £100 you also only get 3gb

The VRAM makes next to no difference in gaming, as long as you have 2+GB you will be fine. The 280 should be a rather nice improvement over a 270, so if you have the money, go for it.

 

[Madmullen]

I have also had a look at the Sapphire and @ £275 I think I will probably go for this card as it has everything I need and I wouldnt have to upgrade for a while.

 

[NeverBackDown]

A 290 is very very big upgrade over a 270. For the money you could get it for it would also be one hell of a deal. Wouldn't upgrade for a long time as well(as you said).

It's a 280x and yes that would be the best choice in my opinion. With this card you should should be able to max out most games at 1920x1080 and 60 FPS if not higher. For very few CPU intensive games your CPU will propably bottleneck a bit but even now the FX6300 is still a pretty good performer.
Crossfire/SLI configurations are often problematic for compatability reasons so that you'd have to use one card only for games which aren't optimized.
