I have a AMD Athlon XP2800 running at 2.08 GHz on an ASUS A7N8 X-E deluxe MB. I think that my CPU is trying to fail. I run mostly flight sim, and want to upgrade my system in about six months. For right now, in case of CPU failure, I would just upgrade my CPU to the fastest that this board would handle. Can anyone tell me how to determine that?
