Choosing CPU for my bro

[James^.^]

My brother has asked me to build a good pc that can make games like COD4 and UT3 look pretty, soo I've decided to get him a HD3850, a p5K-e mobo (haven't really decided. So if anyone has suggestions on a value board please comment), and I have'nt decided what processor. The problem is that I don't wanna put too much money into it cuz I'm looking at the 500$ range (maybe a few bucks more). I've been searching on google and the forum but no luck. If you find any information I'll gladly read it (or watch or listen).

so a new tower / box???

or just motherboard, CPU, ram???

I'll show everything i got so far

HDD 7200rpm
Cooler master case centurion 5
HD 3870
DVD drive

haven't picked out ram because I haven't picked out the motherboard because I haven't picked out the processor.

I really just need help on an affordable processor
I'm thinking this AMD AMD Athlon 64 X2 4800+ would be nice, what do yall think

For gaming, go intel.

Everyone says intel FTW (probably cuz its true). What processor do you recommend that costs 1-125$?? that has a good money/performance ratio
