This is what I have so far:

(samsung spinpoint f3)

gfx (im sure we can improve this, but im not computer techy enough too..) http://www.newegg.com/Product/Product.aspx?Item=N82E16814130625
(evga gtx 550 ti (fermi))

RAM http://www.newegg.com/Product/Product.aspx?Item=N82E16820231358
(gskill ripjaws 12 gb (3x4gb) 1600 ddr3

intel core i5 2500k sandy bridge 3.3 (3.7 turbo boost) and asrock z68 pro3 gen3 lga 1155 intel

which comes out to be 804.92 USD with the gfx mail in rebate.

how can i improve this while remaining in the same price zone of 800?

and also, can you tell me why and how to improve myself, because i want to learn.. i know its not the best, and i want to know how to improve it for future builds. i believe everything is compatible and that itll run on 750w


EDIT: and if its 5 or 10 bucks extra for a game coupon, link me to both of the products

Well you can improve it by not going for 12 gigs, and your motherboard is Dual channel, no tripple channel so u can only go with 2 sticks of ram, Go with 8 gigs of 1600 ram.
