My brother has a Falcon Northwest fragbox from about a year and a half ago. It has a 4600+ AM2 in it (not sure of the mobo at the moment, looking into that...although I know it's SLI). He just picked up an 8800 GT, and I suggested he grab a new CPU to compliment it. I was thinking of suggesting the 6000+ because of the upped cache, and the obvious clock increase, but is there a better AM2 choice in the sub $200 range? I'm going for the best price/performance ratio. How far can one OC one of the better AM2s without messing too much with the voltage? The fragbox is a small case, and has a tendency to heat up...
