Hello there again, I've nearly decided on a rig which will stand the test of time for the time being. I picked these parts having current and upcoming Blizzard titles in mind (SC2, Diablo III and so forth) Please note that my budget is around 1100 US dollars or 850 euro depending on which currency you prefer.
