Everyone I've asked has told me that you can't have a decent gaming PC under $600. I decided to prove them wrong (since I'm broke). So I bought a cheap HP DC5750 desktop for about $50. It came with a 2.4Ghz AMD Athlon X2 CPU, 1gig of RAM, and onboard video (with 128mb of dedicated vRAM). Since then, I have upgraded the RAM to 3gigs, the CPU to 3.0Ghz AMD Athlon X2 6000+, and the GPU to an EVGA nVidia GeForce GT 630 w/2gig vRAM. I added an old PSU fan, and an old CPU cooler for optimal temperature. That all added up to about $170. I can run pretty graphically intense games on low settings at around 20FPS, such as Battlefield 4, Saints Row: The Third, and DayZ. I can run games such as Just Cause 2 at about 30 FPS on medium high settings. All in all, I think I successfully proved them wrong. Any thoughts?
