Is anyone else out there using this graphics card?? Are you having (or have you had) any problems with it? Whenever I play a game (EQ, Madden 2002, NHL2002, etc...) it starts out ok but after a certain amount of time (it varies) the graphics start to flicker... I guess a good way to describe it is to imagine how the screen get's rendered if you were watching it in slow motion... you would see a line starting in the top left hand corner of the screen then tracing from left to right while moving down a line each time... this is what happens (but in normal speed) while playing a game, it starts out with a few flickers then get's progressively worse... sometimes if I reboot and start again it's fine for a little then starts over again... sometimes rebooting doesn't work??? Any suggestions?????
