well I think it would make sense, seeing as how ATI is set to have 64 real pipelines. Nvidia would have to raise the stakes from 32 pixel pipelines and 16 vertex shaders....
Does anybody know what the actual minimum PSU specs are for the G80? From what I've heard, my FS 500W will not cut it. If that is the case, I will get a 7900GTX after the next price drop (that should handle UT2007) and wait on DX10 until they get the power requirements down.
it should be pretty power hungry.
it will have more pipelines, and therefore more transistors. and no doubt an increase in core frequency over the 7900's.
Look at the trends for the alst few generations. The 5 series was 300wat min, 6 was 330 7 is 350. I would say 400w from a good company will be fine for a single one with atleast 25amps on the 12v and 30 from dual rails.
I don't think it will be true water cooling, but infact those pipes with that liquid in on high end fan coolers.
I think I will be picking one of these up sometime next year. (not straight away though. (The GT, not a GTX unless my March bonus is more than I predict.)
