Hi. I'd like to spend maybe ~ $150 upgrading my sli config to pump some more frames. I generally stick to a 1920x1200 setting, and my current cards boast 768mb of ram each. I can't put on anti-aliasing for any first persons though, or I die. Anistropic isn't a problem at all. So, I was wondering if I could upgrade a single card to give me cost effective (and noticeable) framerate gains. I was thinking maybe a 9800 GTX? They're on newegg for ~ $140, I'm just not sure if it'd be worth it. If so, can't I just upgrade one card, and then have them split the load accordingly?
