The parts you have chosen will work together, however if your getting a new Mobo, CPU, Ram and PSU - that's almost a whole system. [missing the OS, new GPU and peripherals]
Depending on your needs/uses for your PC, it's actually much more economical to save up a little more build a whole new system. I don't mean to offend you but your current system is at a point that any investment into it will have diminishing returns. And the parts you have chosen aren't bad for your current system - they simply don't have a great price vs performance ratio [i.e high de-appreciation rate] which will also translate to poor performance gain in practice.
It doesn't cost much more to get a whole lot more performance and bang for your buck; I'm not even talking about high-end hardware or ridiculous $2000 PC build budgets.
Take some time to think about it and tell me your current budget - it's much better to build a whole new PC than to upgrade something that's of age.
And Since you live in the States and plan to make your purchase in November, I'm assuming your waiting for the Black Friday sale??
By buying a new CPU, MoBo, RAM, and PSU I basically am building a new machine, short of an HDD and Optical Drive. I don't see how this upgrade could possible leave me short of buying a new PC in terms of performance. The GPU is just shy of 2 months old. The other components don't need replacing as far as I'm concerned. The HDD has everything I need and I don't plan on dishing out too much money for an SSD. I rarely use the Optical Drive, so replacing/upgrading it is pointless.
The way I see it, I'm only short a new build by the hard drive and case.
Also, I was not waiting for the Black Friday sale, but if Newegg usually has one, I definitely will.
