Re: New i5-655K Build
for pretty much the same price as your cpu and mobo, you could've went with a 1155 sandybridge build, with an i5 2500k which is better than that i5 dual core you have, or atleast an i5 750.
the k series 1156 cpus aren't really worth the premium over the regular 1156 cpus, as those already OCed nicely. so you payed more for an unlocked multi that's not really gonna help much plus an integrated gpu that you're not using.
it's not a bad build at all, but i think you should've asked for some advice before you bought everything though.
