First PC Build

I've always been a console gamer, but what i realize now is that i've been living under a rock my entire life. So, its about time I get myself a PC. I have a tight budget of around $550 USD and a pretty good idea for the build but im just looking for other opinions. I already have a decent monitor, a mouse, and a keyboard. I also have a copy of windows 7 so you dont need to worry about that

Well, heres what i've been thinking........... http://pcpartpicker.com/p/1q9H4

Also, I would prefer not to order the parts from anywhere other than newegg or amazon so keep that in mind if you think i should make some changes. And the wifi adapter is necessary. So let me know what you think.

Just a few minor improvements.

The RAM you chose is overprices and I got you a slightly better PSU and the GPU in there is very considerably better.

The only thing from something other than newegg or Amazon is the GPU but NCIX are a very well known retailer and are good so it should be fine
