+1 on your Hybrid SLI idea and something like this? Remove w/e hardware u intend to reuse ^^http://i137.photobucket.com/albums/q205/batuchka/4xxaf.jpg
Not bad was really thinking of using the 720 i know it overclocks farly good but it was also on the high range for the money i wanted to spend. Which would overclock better e5300 core or the 720 even being triple core would the extra 50 dollars make it worth it.
Alos is it worth the 10 dollars and extra heat i have read able to use the 8300 board over say a 8200 nvida.
