So I was originally shooting for a $500 build, no windows or peripherals included, that consisted of a GTX 750 TI and an FX-6300. However, it is possible that I could get my hands on an older PC (at little to no cost) and I wanted to see if someone here could help me properly update to a similar performance level to the aforementioned build. Right now, I know the specs consist of an Athlon Dual Core Processor clocked at 2.1 GHz and an MSI GeForce 7300LE. 2GB of RAM, and that's really all I know. I know it's a dinosaur but I wanted to see if someone could find me a build similar to the one I mentioned above and see if it would be easier or cheaper to update this build rather than building an entirely new one. Thanks in advance!
