I play TF2 on servers with about 32 people. My current setup is: AMD64 s939 3500+ XFX 8600GTS XXX Edition 2GB RAM I want better framerates in TF2. I run the game at 1680x1050 with 16xAF and 8xCSAA and it gets a little too jerky in big firefights. Even when I turn off AA it is still jerky. This is leading me to believe that it is the CPU that is hindering me. Which would increase my framerates the most? I can get a E6750, mobo, and 2GB of RAM for $350 or I could get an 8800GT for ~$250. Eventually I plan on doing all the above but I want my first purchase to improve my TF2 framerates.
