A person who buys a GTX285 now is an idiot. The HD5850 is cheaper in the UK and offers better performance too:

Things maybe different in the US though. I would rather get a GTX275 and save the money TBH if was getting an Nvidia card.It has most of the performance of a GTX285 for a massively lower price. OTH,an HD4890 has most of the speed of a GTX275 for a much lower price:

3D Vision is pointless for 99.99% of all gamers as it needs special hardware which is not cheap. How many people will be spending £100 for the glasses or will spend hundreds of quid on a new monitor?? This is the real world not the cloud cuckoo land which many hardware enthusiasts inhabit. Most PC gamers are not enthusiasts.
CUDA is pointless for gamers too. I definitely see its advantages though for non gaming use and if anything has made ATI get of its backside and also try to offer similar functionality in its cards too. However gamers only care about GAMING performance so CUDA is a non entity here.
I have never met anyone who is a gamer who buys a graphics card for GPGPU functionality yet. Again they are looking for the fastest framerates for the money they have paid in the games they play.
PhysX only has limited appeal but then MOST people prefer better visuals to physics especially in FPS and other similar types of first person perspective games. Most people want their graphics to be concentrating on the actual visuals as you have a CPU to do other work. If your GPU is fudding around with things the CPU should be doing you are not going to be getting the maximum visual benefit in games are you??
I want my FPS games to look as close to real life as possible. Physics won't bother me so much until graphics improve and the latter has a fair way to go still. A game like Crysis had a good enough level of physics and it does not particularly tax the CPU massively either AFAIK. Most people who watch modern action films tend to be more awed with great visuals then realistic physics. The fact that most action films have non realistic physics underlies this point and Joe and Jane public seem to not care as these movies tend to do very well despite their unbelievable plots. John McClain taking out a helicopter with a car?? Cars jumping through the air and not wrecking the suspension?? Everything exploding even if the Hero breathes on it??
Happens all the time in real life doesn't it??
Considering that most CPUs are criminally underused during games the need for PhysX is very limited at the moment. Eyefinity is also of not much use since most people own only one monitor.
Every single gamer I know only cares for the actual gaming performance in the games they like and do not give two hoots about propriety features.
DX11 on the other hand is useful(if not a currently essential feature) as more and more games will be using it. It is an industry standard. Of course even use of DX11 is dependent if the DX11 features can be actually activated on first generation DX11 cards without making a game run at a very slow rate. This is the reason DX10 was not so successful and DX9 is still in wide use even to this day.
If DX11 was not important Fermi would not be DX11 and the same goes for DX10.1!! Nvidia said a while back they thought DX10.1 was of no real use but it is quite funny that their latest parts are DX10.1 compliant.
