Looking for build advice

You're off to a good start, but there are a few changes I would suggest. I think it would be a good idea to find a way to ditch that MSI motherboard. Here's the build I would suggest, which is a mix of your parts and my suggested changes/upgrades.

I would have made a carbon copy of shortstuff's list, its excellent.

What resolution is your monitor? That affects what GPU you need to be able to play your games. And what games?

Thanks for the tips guys it's much appreciated. My current monitor is 1920 x 1080 that I'll be using and right now my games library is Far Cry 2, Crysis, Fallout 3, and Left 4 Dead. Library is still small because I just decided that I wanted to get into computer gaming as opposed to my ps3/xbox.
