So I'm in the market for a new gaming computer. I have never had a gaming computer before but would finally like to start playing my games without worrying about whether or not my computer could handle it. I play some WOW, Diablo 3, GTA, Skyrim, ets. MMO's and such. I am torn between an i3, i5, or AMD FX 6300. I would like to stay under $850. It seems like everything I have read says that there is not much difference between those (obviously the i5 is best, but spendy). Also, I'm going to get 650 watts and am torn by what graphics card I should get. I am leaning toward a cybertron, but am open to ideas. Any suggestions would be very helpful??
