Here's my two cents. The video benchmark is quite flawed from the perspective of an enthusiast gamer. All of us avid PC gamers know by now that the true test of video cards is that only 1920x1200 resolutions or higher should be used and with ALL settings maxed out in whatever benchmark is being used. This is just my opinion, but if we are discussing the use of the highest end hardware, then use the highest settings - duh! I don't know of any enthusiast PC gamers that use 1680x1050 as their standard resolution. Also, other things were not taken into consideration with this benchmark such as the total amount of power required to run three GTX280s versus two GTX295s. And what was the system setup used? What nForce drivers were used? 181.20, 181.22, or the current beta version? Too many questions and no answers provided.
I can guarantee that the GTX295 quad-SLI setup would have demolished the GTX280 tri-SLI setup had 1920x1200 resolutions been used and all the settings (AA, AF, post processing, HDR, motion blur, etc) maxed out. That's what enthusiast gaming is all about! Okay, I'm done griping
