Alright, so what's a cheap psu that I can buy? If it wouldn't take up to much of your time can I get some links to the psu and graphics cards? Also how much of an upgrade will it be from a gt 540?
I would go for EVGA 500w power supply (http://www.newegg.com/Product/Product.aspx?Item=N82E16817438016) and r7 260x (http://www.newegg.com/Product/Product.aspx?Item=N82E16814131573). Theoretically, r7 260x is 430% better than gt 540.
