Hi guys, I know this is noobish question, but I decided to buy new video card - Gigabyte radeon HD 5850 (I choose between Gigabyte and Sapphire, and decided to go with Gigabyte because it has one aditional year waranty 3/2 years and they seem pretty much the same in performance), but I dont know if it is possible to add it to my motherboard. I have, as mentioned, Asus M3A78 PRO. Here is a review of it with all specs: http://www.silentpcreview.com/article855-page1.html btw. if you told me how to find out for myself, I would also be glad, so next time I won't have to ask, thanks !!!
