now it performs 20% better. took out useless things like windows 7 pro, a atx motherboard, and replaced some stuff such as the power supply, ram, and most importantly the monitor. makes no sense to get a 18.5inch nowadays
It should be noted the FX-6300 can overclock and it's a similar price to the i3 3220. Also, AMD will be keeping AM3+ socket so you'll be able to upgrade for another 2 generations at least with each generation having an expected 10-15% increase in performance like from Bulldozer to Piledriver. And the multi-threading will be noticeable in applications .
