Will video cards eventually reach a peak where they can no longer improve significantly any more?

What I mean is, certain games, like crysis, already look so close to real life that it makes you wonder if games can possibly look any better. Since a GTX 280 can already max out crysis, how much better can video cards and graphics overall possibly get?|||well, as a computer nerd, for the past 10 years i have been thinking the same thing, i look back now and 10 years ago graphics sucked so bad! but, maybe you are right|||games will always look better, you'd look at crysis and say wow this game can't get any better, but when Crysis 2 comes out you'll see it could. GPUs will continue for a LONG time maybe in 80 yrs where we use virtual helmets then ya it might slow down ... a little.|||I agree with you. I already think blue-ray on TV is unnecessary as dvd is good enough for me. I will buy a blue ray when more than half of the disks in video rentals are blue ray.
