The Intel Xeon X3440 was one of the first tier of Xeon processors that featured the (back in the day) new Nehalem architecture on a 45nm process. Nowadays, thanks to Hypertreading, easy overclockling and presence in the second hand market, it still a great performer for the price (close to 20€). When overclocked it smashes its AMD counterparts, performing better while drawing less than half the power. Gaming is not an obstacle at all while you are looking for framerates closer to 60-75 FPS and browsing the web and office tasks are not a chanllenge at all. In the other hand, this CPU lacks integrated graphics and doesn't support any kind of AVX extensions at all. Most users won't even notice this drawbacks while using a discrete GPU or while they are not interested on Xbox 360 emulation.
