I've found an old system laying around that I could chuck an AMD 64 X2 3800+ (2Ghz dualcore) into as well as a ~$200ish PCIe card and potentially get a low-end gaming rig up and running.
Even worth bothering you reckon or is the GPU going to be unable to compensate for the CPU?
I can stuff 4GB of DDR400 RAM and a big SATA HDD into it from bits laying around, but again, probably not much point.
I don't have a spare $1500 to build a _proper_ new gaming rig unfortunately.
