I kinda feel ATI will win this one, after reading various comments posted about the new upcoming nvidia 9xxx series, many don't seem as delighted, also looking at the specs, I have a hunch ATI will WIN.
Think about this:
ATI pricing < Nvidia pricing i.e ATI prices better and cheaper than nVidia (this is a significant factor in winning customers, bang for the buck scenario)
Upcomin ATI 4xxx series is boasting some incredible specs, given the 3870x2 itself is an acheivement, plus the thought of Dual Gpus in further action is something to be looked into (something radical).
If 3 way crossfire or 4 way crossfire boards are relased for intel chipsets, ATI wins price to performance (assuming the needed drivers are out for this setup to work)
ATI's main competition and issues to deal with ATM: 1)Better performance in Crysis needed 2)Better performance in games such as COD4 needed 3)Better driver support needed
If all this is acheived, ATI wins. AMD is smart, i have a feeling ATI under AMD will perform superior to nvidia, PS- ESA from nvidia seems like too much of a waste of time
The future of videcards and high res gaming will certainly unfold in 2008!
