Here are two PC systems I am currently using for testing VGA cards. Both are relatively low-cost machines, assembled mostly from leftover PC parts I had on my shelves. At this time, I only have AMD testing platforms. Intel systems are not ready yet. Rig #1 , for testing AGP / PCI graphics cards. Specs: CPU: AMD Athlon XP 3200+ 2.2Ghz (Barton) MB: Gigabyte GA-7N400 Pro2 (rev. 2.x) RAM: 2.5GB DDR400 (Dual Channel Mode) HD: Samsung 80GB IDE PSU: EVGA 80PLus 600W System: Windows
