What graphics card should i get?

The HD 6850 is faster than both the GTS 450, and GTX 460. And does not require alot of power. So I would go with that. a href="http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007709%20600083901%20600083830&IsNodeId=1&bop=And&Order=PRICE&PageSize=100" rel="nofollow"http://www.newegg.com/Product/ProductLis…/a Requires at least a 450w PSU.
