I'm rather new to PC gaming and decided I want to upgrade my HP Pavilion p7-1414 desktop, specs below. I'm sure most of you don't want to spoon-feed me what I need however, I truly am very ignorant in this field and any bit of help or info will be greatly appreciated. For starters I know I want a good dedicated graphics card but to do that I first need to upgrade the power supply. One that seemed good to me was the CORSAIR CX series CX500 500W ATX12V v2.3 80 http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027 . If that PSU is suitable what graphics card will be compatible with it and what other upgrades will I need to make for it to all work together. Thanks in advance for the help!
