comments: wow o wow todays cpus are such a bottleneck one or two 7800gtx makes no difference! Two 6800u is pratically even with two 7800gtx due to cpu bottleneck! One x800xl is faster(due to better drivers) than any Nvidia card and only slightly slower than one or two 7800gtx at 1600x1200 aa/af!








comments: at 1024x768 the cpu is 100% bottleneck but the x800xl once again is ahead due to ati's better drivers. At 1600x1200 the much more expensive 6800u is only 10% ahead and the 7800gtx is only 18% ahead of the 6800u because its badly being held back by todays cpus so it cant shine. SLI is utterly pointless with todays cpus!





We see a big gain in 3dmark 2003 with SLI, more than 50% but too bad todays cpus hold you back in games so the gains are very small, if any! However one 7800gtx isnt much faster than what an x850xt could get(not shown in review)





SLI is more than useless, it has a 10% cpu overhead so bye bye goes some of your fps! The sad thing is some people dont realize this so they spend $$$$$ on SLI and LOSE performance! The way I see things, dont bother with SLI unless you wanna run 3dmark 2003 and 2005 all day long! There is a difference to the tune of 18%(6800 vs. 7800) but frankly no normal human eye can see a difference, even the x800xl is way overkill!



There are more results but the website is so slow I dont want to bother. If you want a 7800gtx, go ahead, its really only useful for 3dmark 03/05 and other synthentic GPU based tests. Games show small benefits but youd be hard pressed to notice it in actual game play, just benchmarking. Is it really worth $650 for a 7800gtx vs. a $250-300 6800gt(most oc to ultra anyway)for 10-20% more fps in games when a 6800gt just laughs at any game you throw at it?
