Having just moved up from an Ahlon XP3200+ Barton with 1gb OEM Ram and the 6800GT to a Core 2 X6800 with 2GB Corsair Pro PC6400 and an ATI X1900XTX I can say it was very worthwhile. I now spawn so far ahead of anyone else in BF2 that I get the jets and choppers for the first time! I can run CoD2, BF2, and DDO all at max. Was it the Conroe or the combination? Probably the combination, but as a guy who just spent $2500 to game, IT WAS WORTH E VERY PENNY! I have no regrets and y'all can eat my contrails...
It's my Corvette...

Thats great, but you would have been just as happy with a 5000+ or e6600. I bet if you changed it you wouldn't noticve a difference
