And you should be able to use a 2.0 gfx card in a 1.0 slot but with 1.0 performance. If not, really bad tech IMO.
That is the same exact principle in agp, doubling the data rate 1x->2x->4x->8x. They also played with the slot voltage, but most cards were compatible with 1/2 2/4 or 4/8 so they were mostly compatible with any era slot. I'm telling ya dude, its the same scenario. Wonder why? Because when you say you double performance of something people buy it.
