I recently ordered a new custom-build PC: Q6600 2Gb Geil DDR800 2x250gb hard drives in RAID 0 Asus Striker Extreme motherboard Asus GeForce 8800GTS 320mb I also have ordered a 22 inch monitor I've been thinking about SLI and how I could add another identical graphics card. It seems to be the most cost-effective upgrade I could do, especially if I want to game at high res on the 22 inch monitor, right? I've been looking at a few benchmarks on Toms Hardware and it seems that at lower res it makes almost no difference, but cranking it up to 1920x1200 you're looking at almost double the frame rates. Pairing 2x 8800GTS 320mb is faster than an Ultra, which is WAY outside of what I am willing to pay. They can also be overclocked, as can the CPU. Any thoughts/suggestions? I was thinking of waiting until I get my system, seeing how it goes and then waiting until the new cards in November. Hopefully the 8800gts price will fall a little, and I will invest in another one.
