PC Gaming on a budget is very possible in 2013. The HD 6670 and HD 7750 for example both don't require power cables on 275w - 350w PSU's and both are under 100$ GPU's... Best of all at that price point $65 6670, $90 7750 you can play most games at 1920x1080p if you tweak the game settings a bit. No AA, No Vsync, Low shadows, med. reflections, med. ambient Occlusion, turn of dynamic lighting (HDR, Bloom, etc.), and No physics for you AMD users out there...
