2nd thoughts with this build

http://uk.pcpartpicker.com/p/FXqB

I had pretty much settled on most of these parts but I'm having doubts about most of the parts now. I'm happy with the i5 3570k, the HDD, the case. I want 16gb of RAM but not sure what to get. Quite happy with the motherboard but any other suggestions and why? Not convinced with the PSU as have seen a couple people complain about the corsair. Dont want the Kingston SSD as the price has went up. Also just confused with the GPU because there  are far too many that seem about the same and just guessed with the CPU cooler. If anybody could help that would be great because I could definitely use it, thanks

That's a good build. Corsair is one of the best psu's you can get right now along with seasonic, thermaltake, antec, xfx. The memory will be fine it's corsair memory and it's 1866 Mhz. Plus, it can be overclocked, if need be. You did well with this build, even left yourself possible upgrade(s) with another GPU later on for SLI, if you go that route. Enjoy. 

is it the best GPU in that price range though and what are your thoughts on another SSD??
