I do mostly gaming and its been a few years since my last upgrade. I am trying to stay a bit ahead of the curve with a p35 board and quad chip. I would like the option for raid later on, and I plan to OC the chip to 3ghz. I am new to OCing and would like the easiest path to travel. Any thoughts on my choices? I would like to keep the price around $1200. Less is always better too
