I did a rebuild from an old system - I had an old 775-880 Dual Pro Mobo with a P4 3.0 GHZ Prescott processor with HT, my 8600 GTS, and 2x1 GB DDR2 Corsair XMS2 Memory at 800 mhz, a 450W PSU, and a Sylvania 17" PD-80A monitor which has a max resolution of 1280x1024. I also used an 80GB WD HDD and a 250 Seagate, although I don't know the speeds on the drives.
I built a new machine on a budget: MOBO: ASUS M4785T-M/CSM, an Antec 650W PSU, AMD Athlon II X4 635 Processor at 2.9 GHZ, 2x 2GB Kingston RAM (dont know the speed of the top of my head), then re-used my HDD's monitor and video card. I had that other video card lying around and didn't know which one was better.
When I get some more money, I'm going to upgrade my drives, probably to 2x 1TB. I also want to install another 4GB of RAM and upgrade the video card. Any reccomendations for what I should get?
