Another GPU question.

[hobib_ali]

So Im deciding which GPU to buy, I have selected 7950s and 670s

Now the above cards come with 1.5 to 2.0 gb of memory, I see there are options where you pay slightly a bit more and you can double the memory on the cards, so from 2gb of memory to 4gb and so on.

Would it be worth adding the extra 50/70 pounds to double the memory?

Will I notice a difference? is there any point of getting the 4gb versions, or hs anyone upgraded to 4gb cards and noticed a difference?

Cheers overclockers for the help and advice.

Ok I have identifed a good deal,

VTX3D HD 7970 X-Edition 3072MB GDDR5 PCI-Express Graphics Card at £299.00

thats the cheapest 7970 and its got dual fans, with 3gb memory

So 2 of these will be 600 and its the top AMD card

What do you think? value and build?

But one thing that concerns me is:
I have the Gigabyte UD7 mobo on 1366 platform, I think the PCI e slots are 2.1

But all of the new cards state they are PCI e 3.0, So will I be able to use the above cards on my motherboard, its 2 years old but was one of the best boards at the time, it cost me £280 I know its not pci e 3.0 so concerned if the new cards will work, and if they do, will I get the full peformance? or wuold it be reduced due to my old mobo?

oh, i have a single screen set up, i have a dell u27 inch on 2560x1440

I had the idea of running duel set up = better graphics, im just so use to my 5970 xfire
set up, but thses new cards are capable on just 1 card?

Ps the vtx3d card is good yes?
