I've working on a Dell Inspiron 530 that has an old 8400 GS video card in it now. The CPU is a Core2Duo in about the 2.8Ghz range I think, and it still has the stock 350W PSU. I'd like to just find something in the $30-40 range that will refresh this thing a bit without needing a new PSU. The system will see some gaming, but obviously I'm not expecting miracles out of it, just better than the 8400 that is in it.
