i got four ?'s about upgrades

1. The 660Ti and 7950 are fairly close in gaming performance, with a slight edge to the 7950. You could get either and not see overly much difference in performance.

2. On a budget, something like a 212 EVO (~$30) is very good. There's not much point in buying a medium-end cooler IMO, jump straight to the high end and get a Noctua NH-D14 (~$80). Beyond that is the H100i (~$140), but for a small amount more you can get real watercooling which will perform much better in the form of an XSPC Raystorm kit (Depends which one you get, but I advise the RX240 kit at minimum which is $170 at FrozenCPU.com).

3. For gaming 8GB is plenty, though RAM is cheap so upgrading to 16GB wouldnt be overly wasteful.

4. An SSD wont benefit gaming performance, your FPS will not go up if the game is on the SSD. The primary benefits on an SSD is the faster boot times and just faster general system responsiveness. It really is noticeable how much slower a HDD based system is once you get accustomed to an SSD system.
