the gts-u was a very good thing for nvidia in terms of the end user oem buyer, who only cares that he has the 'fastest' and 'biggest' rig out there. all the gts-u is, is a card which still lets them hang onto the speed crown if the v5-6000 doesnt beat it, just enough IMO to keep the reviewers thinking nVidia until the NV20's out. as for it's release date, im sure nVidia is up to it: they have delivered in the past with the NV15 and im sure they can do it again with the NV20..
overall, i dont like 3dfx's approach to high power gaming, as it obviously isnt a future worthy solution. just whacking more chips onto it is going to get tedious after a while and, although it was only for one generation, imagine just how much better the rampage would be if they had at least soem tech to carry over from the vsa-100, a lot less work for their engineers, and surely could mean the difference between an on-time generation and not. just look at nVidia: they have carried over tech from the GPU's they developed nearly a year ago now, and they sure as hell arent having any problems at the moment. even though their sucess isnt totally attributed to their planned future, i think it's just plain counter-productive to have two engineering teams developing 2 different chips. we are witnessing one of the fastest growing industries and companies in the world and even though their end solution might not be preffered to some, it works for the majority of us.
i just wish 3dfx would get off their butt and make something - FAST!!!
