Trying to decide on a CPU for my new budget gaming build. I want to go with a 60 dollar AMD processor - http://www.newegg.com/Product/Product.aspx?Item=N82E16819113336 or http://www.newegg.com/Product/Product.aspx?Item=N82E16819113282 - http://www.newegg.com/Product/Product.aspx?Item=N82E16819113328 but but these are both Dual-core and with a 1 MB L2 cache. Then there is the quad core for 80 dollars and a 4 MB L2 cache - Is there a significant difference? I am on a budget, so hopefully there is not a huge difference between them because I really want to go with the cheaper CPU. I am also going to have an XFX HD 6970 in my build. Opinions or recommendations?
