I'll be honest and say that my understanding of graphics and DX9 and ARB etc is severely limited to say the least, which is why I fully appreciate people who DO understand what Carmack et al are talking about, coming here to enlighten us sheep.
I had for awhile been considering the FX5900 Ultra, but after all the nasty things I read below which, as far as I can determine, are nothing but plain honest truth, I think Nvidia has received its last dollars out of my pocket.
As for ATI having shitty drivers, shrug, Nvidia's drivers have never worked well for me anyways, so I don't think I'll notice much of a difference.
Thanks for all the info guys, it's well appreciated.
