Hi I am new to the site so please forgive if I posted wrong section/or already covered in another thread. I sold my baby, gtx 590 and am awaiting a gtx 680 in the mail (maybe sli eventually), recently upgraded mobo's to the asus sabertooth z77. I just learned about virtu MVP.. Did some research and it looks pretty nifty.. I was wondering who has had experiences with the 680 and virtu MVP.. The benchmarks I saw only put the 680 up a couple, maybe a few percent in some cases... So is it really as good as it seems?
