Depends on game. On battlefield 3 you should expect 80-90% increase. On games that don't support crossfire - 0%.

Ino that every game doesnt support crossfire,
I just mean with games that can lol.

Will it make any difference crossfire @ x8x8 rather than x16x16?
As in will they still run to there potential?

Thanks alot

Afaik you cannot crossfire x16x16. It will work without a problems.

I thought you could crossfire 2 gpus in 2pcie x16 lanes both @x16 bandwidth?
Because ive seen charts comparing the two (x8x8 vs x16x16)

Also could you recommend a psu capable of 2way crossfire for 2 6870s?
ive got a corsair cx500 but thats only got two 6+2 pins

Thanks alot
