If you're not sure what's the geekiest thing you can do with the money, we're talking about either a SLI or triple-SLI setup made out of GeForce GTX 280 cards, hooked up to an nForce 790i SLI Ultra.
Those may be expensive sights but they aren't necessarily pretty with the tri-SLI system looking especially cramped with the GTX 280s basically being high-tech sardines in high-tech cans. Still, the crowded feel does have one bright side and that's performance which was been partially proven by the guys @ VR-Zone. They used three GeForce GTX 280 cards with an Intel QX9650 @ 4.0 GHz-powered system to reach a 3DMark Vantage score, using the Performance setting, of 21350 points. Still not worth a kidney right?
