I agree with the fact that AMD have improved there chips tremendously... and that is great... but they still need some work around the stability factor.

1)As you said you are using it mainly for games and AMD performs far better than Pent for games. It has a 3x more accurate floating piont calculation.

2)If you do anything that needs a 24 hour up time or as much up time as possible i suggest a Pent.

AMD is for gaming and graphics.
Pent is for a server and stability.
