Ok this is what i came up with for you. Click on the attached file once, then when that opens click on it again to make it a bit larger (so you can read it). the other guys here feel free to take a look at what i picked for him and make comments. It's a dual core AMD 3800+, 2 GB memory, 250 SATA hard drive, DVD rewritable drive, 256 MB nVidia card, with a 15" flat panel monitor.
Here are a few things to keep in mind. I don't know if you need/want a new monitor so i included a 15" LCD if you don't want it, that will save ya 100 bucks.
I did not go with Vista Home basic, because Home Premium was a free upgrade.
I added a separate video card since you said you game, if you want to use the onboard video card you can take off what I selected and it will save you 50 bucks. The onboard video is: NVIDIA GeForce 6150 LE Integrated Graphics GPU and the one i picked for you is: 256MB NVIDIA Geforce 7300LE TurboCache.
I added speakers, but if you don't need them that will take off 30 bucks.
I didn't add a floppy drive, if you need one that will add 30 bucks.
I didn't add a printer either.
Total Price $859
Price without monitor, speakers, and video card: $679
ok...i think that was all.
