Currently i have the x600 pro PCI-e, which i run at 500/360, but the 4 pipes are just not enough. I am a casual gamer, and I do some video editing some times, and the x600 is lagging. I have a budget of around $200, and I am willing to buy used or on ebay. I searched the forums around and found that i can get the 6600GT, X700, or the cheap version of the 6800 and x800. Im really not sure which is the best choice, but Im really looking forward to some of the games coming out, and would like to play them on High settings, like Battlefield 2 and Splinter Cell Chaos Theory. thanks
