As almost always fast delivery from Amazon. The packaging was actually safe as ever. Now the article itself: Since I have a 775 he had even socket on the motherboard I had the choice of either a quad to buy or a dual core. The quad-core Q9550 currently costs about 220th Since I mainly play Counter Strike Source in which only one core is supported, I have opted for the dual-core E8400 as it currently the best price / performance ratio. The performance is currently still more than sufficient. Especially since the E8400 in the E0 variant (as far as I know all of Amazon) is an overclocking miracles. I currently run it on 3.6 GHz with the radiator Xigmatek Thors Hammer OC Edition at full capacity Prime stable at about 55 degrees. 4.0 GHz would theoretically be no problem! The boxed cooler of course I do not even installed (: For all those 2 cores even reach this stage a strong buy recommendation
