How can i improve this build? $700-$900

[Al_da_gamer]

I have earlier gotten help with a build, tough i may get more money for my birthday, and so i thought i could get some help from you guys to improve this build. It would be great if it stayed around $700-900, it's purpose is for gaming, and drawing/painting software. PLEASE DO give suggestions or improvements to the build. [NOTE: I really need help picking a Video Card as well ]

a 2GB Radeon 7850 should handle most games on high settings and you can find one under $200...if you can afford it Id suggest the Powercolor Radeon HD 7870 Tahiti

also with this build i would bump the pSU up to a Corsair 500W...its maybe a $10 difference
