I am planning on getting a 770 or maybe a 780 I have a 620w Sea Sonic PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151096
and I was wondering if this is enough power or will I need to upgrade my psu if I do you have any suggestions of what psu.
also I was wondering does the 770 4gb make a big difference compared to the 770 2gb?
thank you
