I suppose I will add my two cents. In this thread, we've got ATI fans ranting about Nvidia, and we've got nvidia fans ranting about ATI.
Personally, I have own a Voodoo3, a Geforce 256 DDR, a GF3 Ti200, and a GF4 Ti4200. Right now, my desktop is running with a 9600 Pro, and my notebook is running with an M9. Every one of those cards/chips has served me well in the past.
At this point in the market, I see ATI making all the right moves and I see Nvidia stumbling over themselves. Competition is a beautiful thing, but Nvidia has to plan on the same soccor field. Granted, its the developers choice what to do with their game, it may be an asinine decision to exclude ATI cards, but thats their decision to make.
And honestly, Bridge It sounds like a lame game to me.
