To run Nvidia's maximum supported AA mode at one of the highest available resolutions available on a card that's equivalent to the $150 9600GT? That's hardly representative or reasonable. I also have a 640MB GTS and if performance and IQ was a real issue there are products out there right now that are much faster (and appropriately more expensive) that I could trade up to today.
People will always want more and it wont be any different the day after new hardware is released. But how many people do you actually see nowadays complaining about performance in games besides Crysis?
Check the sigs of some of the guys criticizing Nvidia's current product strategy or ATI's lack of competition....you'll see that they're running 2 and 3 year old hardware. A lot of the noise is coming from guys who don't even buy the stuff!
X16AA isn't nVida's official maximum supported AA mode with a single GPU. x16 is x4 MSAA with the CSAA feature -- we're not talking x16Q - which is x8 MSAA with the CSAA feature. DirectX 10 content takes a pretty substantial hit here at times and as time passes will be much more important. There's things like adding AA, resolution and TA technologies to consider as well. Personally targeting DirectX 10 content!
I disagree with you Trin, that's all. Understand the point of people getting tired of their hardware if they have it for some time.........but DirectX 10 needs a good kick-in-the-ass and feel this may be a very important reason for gamers to consider upgrading -- not because they're tired of their old toy in the Pram.
