Another user with an i3 mentioned this CPU a couple days ago, and it looks like it's more or less an i7-3770 with no integrated graphics card, which isn't necesary, anyways. I've been feeling a bit of a want to upgrade my computer, and the stronger CPU would be really useful in Guild Wars 2, especially where there are a lot of people around. Also, it'll probably be a more futureproof CPU, just because of the extra cores and because dual cores are starting to fall behind.
What brand is your mobo? Because two manufacturers that I can't think of block their consumer grade boards from accepting Xeon processors in order to push their server lines. Just check to see if your board is compatible before ordering, if you can't find your specific board just google around for a few more by that brand. As long as you don't get lots of "It didn't work!"s it should be fine.
