I'm wondering if the card may be getting hot and slowing down because of
that? i replaced the heat sink a good while back and I got more than enough
cooling on the case. The heat sink has a fan and maybe it is not turning or
something. I did blow out the dust a while back and I do have filters over
the intakes to help some.
Some Nvidia cards can go into a slow-motion mode when they overheat, I
had that happen on mine (it was a 6000 or 7000 series, I think) when
the fan died and I didn't realize it. The slowdown was dramatic in
those cases. It would usually happen if I was playing a game or a
video, suddenly it would go 2 frames per second. I'd stop the
game/video, and even things like opening a window were slow. After a
minute or two, everything would be back to normal speed. Eventually I
learned that the card was protecting itself by switching to an
ultra-slow mode to try to fight the overheating.
nvidia-settings may be able to show you the temperature and speeds on
your card. You might need to add:
Option "coolbits" "1"
to the device section in your xorg.conf to get it to show you some of
those options if they aren't initially visible.
I appear to have another issue to deal with right now. This is weird.
When I type in any nvclock command, I get something like this:

I guess I'll have to take the side off the case and use the infrared
thingy and look to see if the fan is turning. I'm not sure what is
going on with the buffer overflow error tho.
