Which is better for gaming with overclocking kept mind? The e5800 or the x6800... i'm super broke and i've managed to put together system for $130 ( asus mob, 8gb ram, gtx 275, 160gb wd caviar se, thermaltake heat sink, case w/ old dell xps 750w psu). I have the option to chose between the two cpus at no extra cost. Help Please.... Thanks in advance
