New Graphics card needed

[snakegb]

Hi all,

at the moment i have 2x560 sli running at res 5760 x 1080 (3 x 24" Monitors)

i do play games at this res like BF3 , Need for speed, Cod, guildwars 2 etc

am finding frame rates are low

so to cut to the chase i need an upgrade i have £600 (No more) to spend my motherboard is Msi P67A-GD53 the spec says both crossfire and sli so dont mind

so whats the best i can get
thinking Nvidia 670 or Ati 7970

yes am sure that my corsair 950 would handle them,

but acording to the review am seeing ie on BF3 the 670 performs better than the 7970

looking at going for the Nvidia option as i know the layout of sli setup and last time i had ati found the driver software anoying

so looking at this card,

i know it uses 2.5 slots but dont think its a problem in my pc

if anyone can suggest a better 670 for the price ill look at it

Hi Guys,

the card i was looking at isnt avalible any more now, so am looking at a
EVGA 670 Superoverclock but was wondering as am running 3 screens and play skyrim with hd mod am reading that i would be better to go for a 2 x 4gb cards.
does it work like this

2 x 2gb sli cards makes 4gb video memory and 2 x 4gb sli cards make it 8gb video memory.

still pondering this

3 monitors (5760 x 1080)

better with
2 x (sli) EVGA GTX 670 FTW - 4GB = £740

or

1 x GTX690-4GD5 - 4GB Asus GTX 690

acording to this website it performs better
