I am researching gfx cards atm and I found this particular gfx to be great for its value http://www.newegg.com/Product/Product.asp?Item=N82E16814121174 . would this gfx card work in a regular pci slot on my motherboard? because i have no idea what is different between a regular pci based gfx card and a pci expressx16 gfx card
