PCI X16

I am thinking about upgrading my GPU to a Nvidia GTX 280. I have a Asus p5b deluxe motherboard which has PCI x16 1.0 and the 280 uses 2.0. Will there be any performance set backs if I don't upgrade to a 2.0 motherboard?

It wont make any differance at all your graphics card isnt even using the full capacity of the PCIE 1 X16 slot.
It may run faster on a differant Motherboard but then differant motherboards give differant results with the same hardware anyway.
it certainly isnt going to make enough differance for it to be worth changing the board.

They had an article on it, but it's dated enough now that it doesn't include the top end graphic cards like the 4870x2, GTX280, GTX295 or the 4850x2. I'd guesstimate that if there's a hit at all it will be small.

yes, but they did not answer the real questions of what would cause it to be fully used.

An analysis of what would cause saturation so that people could be given a proper answer instead of conjecture.

usually if it an actual gfx card test their is some investigation of why a card will performa or not perform as it should but this lacking. that leads to FUD among forums especially.
