The last two machines I bought were factory refurbs. They went back to the manufacturer and were stress tested, parts were replaced and they were sent back out with base OS.

I'm running an i5 3.3 Ghz quad with 10GB ram that I got for $300 US. If I can find a modular power supply that fits in it, I'll get a 750 ti low profile as the supply in it only has 240 watts but the 610 card I got is running this and everything else I play. Is it brag worthy? No but I still have a hard time wrapping my head around paying $600 for a vid card so I'll make due.
