here is my specs. I plan on just building one from the ground up though
amd athlon xp 2800 2.1 ghz
1024 mb memory
128 radeon 9600
That's actually not a bad rig. Your biggest problem appears to be the video card. I bought a GeForce 6600 earlier this year and it works pretty well at most games. It chugs pretty hard on GRAW, though. I recently bought a GeForce 7600 GS that seems to handle GRAW just fine so it should be able to handle other games pretty well, too.
But I see you're probably an ATI guy. Nothing wrong with that but people seem to be more comfortable with one brand or the other and not really switching between the two. I stopped buying ATI video cards because of the driver of the week thing and switched exclusively to nVidia cards. That's just my personal preference, though. I can't make any recommendation on ATI cards because I just don't know their product line that well.
I understand the desire to build/buy a new machine.
When I build a new machine I usually try to just buy a new core (cpu/mobo/memory) and reuse most things like my case/power supply, hard drive, floppy, optical drives and even my video card. The last machine I built a couple of weeks ago I couldn't do really do that.
I waited so long to upgrade the technology that all I could really use from my old machine was the case, floppy and optical drives. The new motherboard required a new processor, new memory, new video card, new power supply and a new SATA hard drive because the mobo didn't have enough PATA ports for my old IDE hard drives. It does have 4 SATA ports, though.
At least now I have a machine that I can upgrade again. The CPU needs to be upgraded (it's only a P4 541 3.2Ghz) and the video card isn't the fastest thing out there (another GeForce 7600GS). It has the right CPU socket (LGA 775) and video card slot (PCI-Express). Most of my other machines are Socket 478 and AGP (except for a PII box and a PIII box for playing _old_ games). I wasn't happy about having to spend over $900 to get that and don't have a machine that's even close to cutting edge.
Let us know what you build/buy so we can share in the cool factor!
