the fans starting to make funny noises when it hits 79-80 degrees C. As far as performance, i can still run every game maxed out 1900x1200 except crysis, oblivion (fully modded), Age of Conan beta, and neverwinter nights 2 gives me trouble in certain spots. i can run 3 of those 4 at 1680x1050. crysis just doesnt count XD.
after playing the AoC beta i've convinced myself im not happy with it anymore. great card but it's gettin old. just a shame there's nothing worth upgrading to lol. If I wan't to SLI 9800gtx's i gotta buy a new mobo too ;p and im still not fond of the SLi idea. but july is so far away and id bet 20$ that the 9900's will be delayed till fall or later.
