Hey everyone, long time!
How have you all been, and for those that don't remember/know me -- the question still applies

Well, after five and a half YEARS of Pentium 3 rigs, I've finally bought a new tower. My question was, besides the obvious (like going up to 2GB DDR2 ram, and getting away from the integrated 6100), I was wondering how well this'd hold up with some newer games. My main concern, more than anything, was I didn't have the time to lapse the few things I'm still shady about in PC construction to make my own rig, but more importantly, I was additionally constrained by cash. Also, I was looking for something Vista-capable (and more importantly, Vista
logical).
My new tower:
AMD Dual-Core x2 4200+ (2GHZ FSB)
1GB DDR2 533MHZ (motherboard has 16GB capacity; 800MHZ limit)
Integrated nVidia 6100 (will go to a nVidia PCi-Express card later -- as stated, budget)
Sound Blaster Live! 5.1
Belkin PCi WiFi
200GB SATA-2 HD @ 3GB/s
Media Card reader
2 DVD-writing drives
