Is the performance hit bad if you run a PCIE 2.0 card on PCIE x16 ?

Ok well my brother has a motherboard with pcie x16 not 2.0 and if he got something like a 6770 would there be a big difference in perfomance. Like instead of 50fps you get 30?

Its Very Unlikely That Youd Have Any Kind Of Performance Hit At All, Provided The Rest Of The Hardware Is Fast Enough To Feed The Card Data At A Sufficient Rate.

There should be no noticeable difference in performance as 16x PCI-E 1.1 is still enough bandwidth for that card. You can only see the small difference in synthetic benchmark results but not that much. The real question is if the motherboard is fine with PCI-E 2.0 cards (early 1.0 boards were not up to standard and may need a BIOS update if it works at all) and if the CPU can keep up ^_^.

True.

I had an issue once trying to upgrade a video card, it fried my motherboard, I end up building a whole new system because of it.
