That would probably depend on what you're playing or doing at the time. Games and video depend on entirely different resources, or can rather, so it would depend. That question would probably be better answered by one of the more experienced gamers but I'd say not more than 2-3 fps in reality based on my experience and the benchmarks listed here:

it says PCI Express 3.0 x16, how do i know if the graphic card will fit in my motherboard? http://it.gigabyte.com/products/page/mb/ga-78lmt-usb3rev_50/specs/
 



how slower? like 10 fps or 1 fps? anyways cooler master elite 330
