I don't think it's as simple as just buying a GTX580. You can't just take out an 8800GTS and stick in a 580. What's the rest of your system specifications? Will your current power supply handle the new card? Is your CPU fast enough not to bottleneck a card that is probably five times more powerful?

I think system is perfectly capable of running a GTX 580 maybe upgrade the PSU to 700W.
My biggest concern is can GTX 580 compete against next gen consoles ? .And other thing is when will next gen consoles arrive ?.lastly i always prefer to play PC version of games because they out smart console counterpart in every way.But those PS3 exclusives are superb and there's no way get those games unless buy a new PS3.Then again is it worth of buying a new PS3 for just to play few exclusives ?
How about keep the 8800GTS(G92) and buy a PS3 this holiday and upgrade the GPU to 28nm one(GTX 680 DONT KNOW FOR SURE) next holiday?...........any suggestion would be great...............sorry for too many question
With that system, the 8800GTS is holding you back badly. Also, I don't think you need to get a GTX580 unless you really want the fastest card money can buy. I would suggest you wait until AMD launches the Radeon 69xx series. This will drive prices down on the current models, and enable you to pick up a slightly lower-spec card (or two) for cheaper. Who knows, if you shop smart, maybe you can afford both the PS3 and a new GPU.
