I'm building a new budget gaming rig around an HD6870 1GB, 128GB SS, and 8GB of DDR3. I haven't picked a CPU or mobo yet, but I'm leaning towards an i3-2120. I'm trying to keep my budget low, and I feel like something like an i5-2400 (or even 2300) might be more than I really need, or even get bottle necked by other components (correct me if I'm wrong, please).
My main question, though, is this: can I use my 4.5 year old 500w Silverstone power supply (http://www.newegg.com/Product/Product.aspx?Item=N82E16817256037) to run this? Obviously I'd need more power later if I want to go Crossfire or add more RAM, but can I keep this old thing for now?
I've actually already purchased this new PSU (http://www.newegg.com/Product/Product.aspx?Item=N82E16817341048), which will only cost me $40 after rebate, but 650w is clearly overkill. Should I send it back and save my $40 (minus restocking fee)?
