Nvidia 295 gtx

This is the card I currently am using. I constantly (depending on the game its more or less) get that annoying driver crash that appears to have been going on for quite some time. Interestingly enough with most mmo's I get a slight freeze and the game comes back after a couple of seconds. Black ops though it's a toss up which usually ends in the game coming back but at times it does crash the whole game. Fallout vegas is probably a 99% chance the games not going to recover and I end up having to hit shift 5 times to get the sticky keys prompt to come up which then allows me to exit the game and restart. Oddly enough I've found with Vegas if I delete my saves often and re-save it happens less (somewhat) frequently.

Why am I posting this? Well, I'm looking for information. This error (nvidia display driver stopped responding) apparently effects all (ATI/Nvidia) cards and is a function of windows. Apparently you can go into the registry or some such and hack fix it or something. I don't feel I should have to though.

My question I guess is, what cards/drivers don't seem to have this problem as much? I understand the 295 gtx is a bit old and I'm looking to upgrade in the reasonably near future. I'm currently running windows visa 64 bit with 6 gbs of ram. An I7 processor @ 2.67 mhz and an 850W PS.

More than anything I'm just sick to death of this error constantly popping up. Any help advice would be greatly appreciated.
