Here is the list that I have so far. Probably all I will need. I built my pc back in late '09 with the AMD 9950BE 2.6ghx, gtx core 216, and 4GB ram. It has gotten really crappy and slow. There are several things that I need some advice with though. I am running a 750W thermaltake PSU that I bought when I built the computer and am not sure of their lifespan. Think it needs a new one or just keep the one I have now?

I also have the 7950 picked out but I haven't found a release date or an approximate one for the HD8000 series. Not sure if I should wait or if I should just bite the bullet and upgrade now. I want to run current and next gen games like ArmA 3, Watch Dogs, Hitman: Absolution, etc. My current GPU can barely handle ArmA2 at medium setting at 20FPS.

Motherboard is something else I am not sure on. I don't think I need one of the super fancy $300 ones because I only use 1 GFX card and a couple hard drives. Last thing is the SSD. I am on a bit of a tight budget but I am not sure if going from 128GB to 256GB is worth it. I want to install windows on it for speedy boot and loading, and my fav steam games like ArmA 2, to get rid of micro-stutter, but I barely have any steam games installed out of my whole library and it is already at 320GB.
