hi, i have recently brought a mac pro early 2008 2.8ghz 8 core 10gb RAM, currently it has dual 2600 xt 256mb graphics cards in it and its really starting to show its age interms of graphics performance and i want to upgrade the graphics card in it to give a bit more performance. i have chosen a GTX 650 Ti BOOST pc card from MSI, heres the link: http://www.pccasegear.com/index.php?main_page=product_info&products_id=22993 i have herd of people running a 650 ti in a mac pro, but not a Boost edition one, has anyone seen this done? will it work? i run mountain lion 10.8.4 btw also does it matter if the card is factory overclocked? will it make my mac spaz-out? thanks.
