an ATI Radeon x600 with 256MB of video ram. It's definitely the oldest part of the machine, but the performance has been fine for my needs. Also, 2GB OCZ pc3200 ram, two SATA 2.0 drives in a RAID 0 array. I don't remember the specs on the motherboard, but it's pretty beefy as well.
I'm running a dual-core AMD 64 6400+ processor, and would really like to see better, or any, multiprocessor support. When I'm running a medium size game with several battles at once, my computer slows to a crawl with 100% usage on one core, but nothing on the other. I realize that divvying up the processing tasks between multiple processors is a computational challenge, but I think this should be a priority - It has a drastic effect on gameplay.
