I support nVidia with my GTX480s in SLI. I would hate a GPU world controlled by CPU companies.
Sadly it is the nature of the beast mate. Any company that could, would. What I mean is if you put either in the driving seat (AMD/Nvidia) they would be as controlling as they could get away with. They have both done things that are quite frankly rude and insulting over the years (rebrands ETC) and the early 6 series cards seem to be no exception. Sure, they may be based on a different core but the bottom line is that right now pound to performance or bang for the buck they are no better than the 5 series. Infact, they are actually worse. A basic egg cooled 5830 can be had for a song ATM (£140 or so the last time I looked).
I don't want to see Nvidia go under I just want to see them change their attitude, drop the arrogance and give us good cards with good cooling for good pennies. If they can't manage that and blindly go on turning out tosh and hoping we will buy it (which is what they have been doing for the best part of two years) then, well, they deserve everything they get.
Of course there will be serious repercussions if that happens, AMD will just take the outright p*ss. But all we can do is hope I suppose.
I do feel that the only surviving GPU manus soon will be AMD and Intel though as that's the way things are going and Nvidia are not in that market.
What Nvidia really should have done with their successes was invest into a CPU. The possibilities would have been endless. I mean, think about this...
Nvidia CPU with onboard CUDA, Physx and directcompute (and opencl). That would be far more appealing (meaning you could fold with a CPU and use any old cack GPU) than having to buy an expensive hot card. Yes I know with the 460 you can do all of that but that's one card. No company can survive on one product alone.
