I use AMD. They work fine. BTW see if that chip is a Barton chip. The FPU on that series is way better than the older AMD models and runs cooler than the older models. In fact, the Barton chips are cooler all around and run better. An AMD 2.5 barton will run better than an AMD 2.8 non-barton and run cooler. My only complaint on AMDs is that they overheat more when playing games but that solvable by buying a better fan and perhaps an aux fan. Again the Bartons don't appear to overheat as badly and I can run Hitman 2 or other games without rebooting issues like the older chips did. In any event, I've never had a reboot from running a p5 render.
