Sapphire 7870 ($185) http://www.newegg.com/Product/Product.aspx?Item=N82E16814202025
XFX 7870 ($225) http://www.newegg.com/Product/Product.aspx?Item=N82E16814150605
Saphhire 7950 ($240) http://www.newegg.com/Product/Product.aspx?Item=N82E16814202026
Wondering if 7950 is worth it over 7870 for the price and if it will be bottlenecked by my processor (AMD Athlon X4 630). Also if the XFX is worth it over Sapphire 7870 because of the lifetime warrantly.
