Was going to sli 7950 but realized that id have to upgrade my psu(currently at 750w)


my question is if i got this http://www.newegg.com/Product/Product.aspx?Item=N82E168... and sli it would the 750w be enough



i kno 670s use less power not sure tho and would i get similar performance out of the two 670's over the two 7950's



i also heard the 680's drivers dont work well with sli anyone have thoughts on this




Should i get the 680 or the 670?

These cards that i do get will be used to play games like bf3 or farcry 3 fps and some mmos

My current comp specs
mobo- ASRock Z77 Extreme4 LGA 1155 Intel Z77
Cpu- Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo)

double up on 7950s or 7970s. even if you have to upgrade psu, it will be better, and cheaper. Also, your old psu should have some retail value.

ATI/AMD=Crossfire/CF
Nvidia=SLI

Both 680 and 670 is fine for SLI. But do note that 670 do not use less power than 7950, but is faster. Shown here:

But I think you should ditch out these idea. You already have a 660 Ti and you should go and SLI that. 750W Crosshair? You mean Corsair? TX750 should be fine for 660 Ti SLI.
