Hello, below is my new updated build thanks to everyone whose been so helpful here. Please give me any last thoughts/changes I should consider. This is my first build so I don't know much. The rig is mainly going to be used as a graphic workstation and gaming. I've never overclocked before, but it's something I'd like to try if it'll better the performance of this build. The total comes to $670 including tax + shipping. I'd really like to get this down if at all possible to around $600. If anyone has any suggestions, that'd be great. I'd also consider switching to AMD if that'll make it cheaper. Here's the build. Thanks again for all the help thus far...
