On games that don't support crossfire - 0%. marcd2011 April 8, 2012 10:02:53 PM 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?

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 Sunius a c 291 U Graphics card a b V Motherboard April 8, 2012 10:52:35 PM this one should be good: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
