okay, I tried EVERYTHING, and I still can't get hl2 to run at fast speeds on my 6800, and I guess I will give up and just belive everyone when they say my processer is a bottleneck. so, I looked at newegg for a fast processer, and found an amd 3000+, 400 fsb, not 64-bit, but I think it will do. but it's OEM, $147. good price? I hope so. but will my heatsink work with it? since it's oem, it probably will not have anything put a processer.
