As of this post, I haven't yet received the new parts. They should arrive in a couple days though. My new motherboard has a "core unlocking" feature that may be able to turn my triple core CPU into a quad core one. I may hold off on that though as I think I'll have more than enough CPU power as is. I've seen similar setups on YouTube running both Skyrim and Crysis 2 maxed out.
