Help with choosing a processor?

Hi,

I am interested in buying one of two PCs. They have very similar specs and price except one has an AMD X2 4400 and the other an Core2Duo E6550. Casting everything else aside, which processor is better for gaming and video encoding?

Thanks.

Hi All

Thanks for the help. I'll be getting the intel then!! It comes in a sugo 1 case, so what's the best £150(ish) graphics card I can get for gaming that won't melt my setup? I used to have a shuttle and that got really CRISPY!

Thanks.
