Im kind of new to SLI if you didn't already notice.
No worries, you have to start somewhere.
wow... sorry about that. I thought I read somewhere that you could sli two different GPUs. So I guess the GPUs must have an identical core or something?
Unfortunately, you need the exact same GPU for SLI. Crossfire is a bit more forgiving, allowing you to use GPUs that are effectively
the same, like paring up a 6990 with a 6970 for an effective 3x 6970 setup. If you want to SLI your 8800GT, you'll need another 8800GT with the same amount of memory and preferably, the same brand.
Really not worth it with a card that old, you'd get better performance just buying a single current gen card and it will use a hell of a lot less power, generate less heat and won't suffer from micro stuttering.
