thx for all comments. just ran 3dmark05 again twice and scored a little lower 7221. i just think this 3dmark thing is bul**** or maybe just the 64-bit environment.
as for the game performance, i'm happy wid it. especially hal-life 2. cs:source has greatly improved it's graphics after valve released an update for XP64 and dual-core optimization. now i just bought an extra gig of ram cuz 64-bit gaming are memory hungry. used up over 1gb of space just to play cs:source
