Should I get a different HSF or will the stock one that comes with the retail chip be good enough? I don't plan on OCing too much but at the same time I want to make sure if I do stays cool. I've been looking at the ThermalTake Venus and the Thermalright XP-90. I've put almost $600 into this upgrade in the last 2 weeks between new video card, CPU, mobo, and RAM that I don't really wnat to put anymore $$ into but on the other hand whats another $35.
