I have had my computer for 3-4 years, and I have used it a lot, and I have never had any problems with it until the past few months. Recently, though, I am getting a lot of problems during gaming. After playing a game for a few hours, I get what I refer to as "texture stretches" where the texture of an in-game item stretches out of the surface it is on. These texture stretches tend to go far as far as I can see from the corner of my screen, are triangular, and disappear if I look away from the source (the object the texture is stretching from). I have also noticed that my graphics card idles at 60-65 degrees Celsius, and hits 80-85 C after a few (2-4) hours gameplay. Very recently, my display driver has started crashing and recovering during gameplay after a few hours. I have never had any of these problems before, what on earth is going on?
The problems occur during any game, regardless of settings, but high end games cause more problems in a shorter time (Left 4 dead 2 is the worst).
I have not overclocked anything in my PC, ever.
My fans are working fine, I even boosted my mounted graphics card fan speed to 45% (default is 31%).
Its in a closed case, not near any heat sources, and the temperature of my graphics card or CPU does not change, regardless of my room being cold or hot.
Windows Vista Home Premium, Service pack 2

oooh thats a nice card. your cpu will definetely be bottlenecking it though. youll get far from as much performance out of it as you otherwise would with a heavier cpu. might also want to consider ram upgrading then. (4gb)
if you dont want to spend a lot of money its rather pointless to get this card, its just too powerful. not to mention youv'e been playing with a rather old card so this is a very big step up.
id sooner go for a 5650 or 5750, 5770 for your config, all of which will perform very well.
