hi i was wondering if anyone knew how much less performance i would get running x8 or x16 SLI\crossfire and if tis worth the extra cash getting a x16 x2 as opposed to a x8 x2?
More aboutdifference crossfire
8x8x vs 16x16 is like 4 to 7 % IMO its not worth the extea money even with 2 HD 5770s xfired you would be maxing most games out, So if your getting 87 fps in a game the 4 to 7 % would be about what 4 fps ? not really a conscern.
Less your trying to max Crysis 8x8x is just fine.
Niklas is correct, in fact its more like 3 percent loss on each 8x slot.
Unless you are trying to run very powerful cards like the GTX 480, the difference with x8/x8 and x16/x16 is barely noticeable.
It depends on the resolution too,for resolutions like 1920x1200 or lower,there is barely any difference,but on resolutions like 2560x1600 especially with AA/AF,there will be like 5-10% difference(depending on the game)
