Right now, I have an 8600 GT, with a P4 3.4HT. I was going to do some upgrading, so I put my graphics card on craigslist a while back, and someone has now offered to buy it. So I was wondering, will a new graphics card help much at 1440x900? By new graphics card, my options are the 8800GT 256, either of the 3850's, and the 3870. Now, I game, but not extensively. I will be buying upcoming games, but my biggest concern right now it TF2, which I believe the ATi cards do better in than the nVidias. Also, I think I can manage the 3850 on my current PSU but I would have to buy a new one for the other cards. So what I asking is, which card would you recommend, and a PSU to go with it, and would that make much of a difference in games with my processor.
