finally got a new graphics card installed. it is a Gigabyte GTS 450.
it still has a couple of glitch in it probably cos one stick of ram is out due to it being faulty.
with this new graphic card i was playing GTA IV and i just downloaded speed fan, the max temp i get from playing GTA IV is 76 C is this too high? today is supposed to get to 40 degress cos it is summer. i dont want to have to pay 150 for a new one.
