I am looking to build a budget gaming box, mostly for SWTOR, but I am looking to get away from my Xbox and back into PC gaming. For now, I'd like to keep the build in the $500-600 range. I recently found an i7 920/X58 combo on craigslist for $200, and I could add 1x3GB of ram and a 4870x2 for another $100. I realize that the 9xx i7 are about to be two generations old, but is it still a wise place to start a build in 2012?
