Hello everyone! http://pcpartpicker.com/p/tUvu
That is, my setup which I'll be purchasing may-july.
Anyways, my budget is $550, so I'm tight pressed to find great, budget friendly parts. I've already asked a few friends to help with this, one suggested changing the CPU from a Phenom II to the AMD FX-6100. However, is there anything else I should add?
(Note: I know about the OS, I already have a windows 7 Home Premium 64x, and I could always get one through means)
There's no need to get the FX 6100. The phenom x4 965 will run circles around it in games. You also don't need an aftermarket cooler right now. The stock cooler that comes with the CPU will work fine.
As for the GPU, I would recommend you change it to the HD 7770. It'll get you far better performance than the GPU you chose. I also switched out your monitor for something far better for not much more than what you had originally chose.
