Nvidia announced that their next line of video cards comes out in February 2008. Based on your experience, what do you think we can expect in terms of speed and price? Will the top model of February be able to at least double the speed of 8800 GTX?

doubt they will even if they are announced too.

Im going to have a stab at the GTX + 25%
 Just a guess for a laugh any advance ?

          Sorry but no idea really thats the big question if we knew we would know if we should buy the 3870/8800GT/GTS or wait and if we knew and waited they would loose sales.
    Mactronix

Mactronix, thats my guess too. 25-30% over GTX. I intend to spend money on 8800 GT in the beginning of January and it will suck extremely if only a month after that comes out a card for the same money that's 30% faster.

your going to get a 8800GT for a P4 Willamette?

 
Anything better and he will still be bottlenecked by the processer, as he already is with an 8800GT. Even with my stock clocked E6600 Core 2 @ 2.4GHz is bottlenecking my 8800GTX, but after about 3-3.2GHz the processer is not bottlenecking my overclocked 8800GTX @ 651MHz core/1525MHz Shader/2000MHz memory.

woooot 9800

 
It doen't even exist yet, more hopeful rumors again. The last time I believed that 9800GTX rumor it put off my purchase for a new graphics card that I needed badly for my new computer. I waited three months for something that wasn't going to happen, what a waist of my time!

i doubt it... but it'l be one hell of a card if its ture

 
Of course not. I plan on buying entirely new system. The CPU will be Core 2 Duo E6750, but if prices drop - maybe E6850 or Quad 6600.

Unless Nvidia has added dx10.1 I would guess it to be the 8800GS as they need something to compete against the HD3850 in price per performance.

DirectX 10.1 is at least a year 1/2 away from massmarket, game companies are not going to support an API when only 2% of all PC gamers have DX10.1 and all others still only have DirectX 10 hardware. That would be a waist of Development time and money well spent on enhancing our existing supported hardware.  
 
Heck we as of now don't see big differences between DX9 vs DX10 is Crysis and when you change the configuration files to enable hidden features in DX9 that pretty look much the same as DX10 with better performance in DX9 with it looking much the same.
 
Don't get on that DirectX10.1 hype wagon when Dx10 doesn't look all that much better than DX9!

if theres no difference than u get higher fps running crysis in dx9 mode

 
 
Yes I get 60+ FPS in Crysis with most in-game setting on high & medium 50/50. Vista will be a lot better when SP1 comes out.
