ADDITIONAL COMMENTS: Trying not to break the bank now, but would like to be able to upgrade (especially RAM/ GPU) in the future. The target price range listed is not including Windows 7 or a new monitor as they're not absolutely necessary, though I included them below because if I can find a good deal I would very much like to upgrade both. The total for components listed is around $800 excluding OS and monitor, so I was hoping for some advice on where I might be able to cut costs but still have a good base for a few years. Thanks for any and all advice!
As above has I may suggest a change to AM3. AM3 will have enough performance for you and will allow you to upgrade to new processors later on. It will also be a bit cheaper than a i5 build. 1156 gets no more processors so an i7 860 is your highest upgrade.
Your choices seem pretty good, however I'd swap out the HDD for a Samsung Spinpoint F3 as they are generally regarded as the best. Also change the PSU for a good brand such as Seasonic. I'm thinking you might need a little more Wattage too if you wanted to upgrade your graphics card later on. If you were just looking to Crossfire that 5770 then I'd suggest a 550/600W (however you say "no crossfire"...), but you might want to go further.
I would definately drop to a 500gb HDD, the spinpoint everyone mentioned. Personally, as a gamer/internet surfer/movie watcher, I have never actually come close to maxing out a 500gb hard drive. A 500gb will save you about $45.
Go with Phenom II X4 955 and an AM3 mobo to save some money. AMD gives you the freedom of upgradibility, so if you want you could go even cheaper with the CPU knowing you can upgrade it later. Posibly even dropping the CPU a bit in order to get a better GPU (5850 is a beauty to work on your new monitor)
