This build will be alot better. You need a K version of a cpu if you plan to overclock, and the 4670k is the newest and best i5. Next, the motherboard. This motherboard will suit all your needs fine, and will support SLI if you want to do it in the future. Next the ram, I always suggest go 1600 or faster ram. Finally, for 7 dollars more you get a bigger power supply and a much more reliable. Rosewill is Newegg's house brand and their psu's tend to be crap.
