Hi there, I recently got a second monitor and was wondering if I should upgrade my graphics card of if my current one is ok. I'm currently using a 6850 and noticed flickers when i hooked up my second monitor. I have since dialed back my overclock to the default clock speeds and have no problems. I also noticed that the temperature went up about 10 degrees since. If I were to upgrade it'll probably be in the $250 range. I would appreciate your advice.
