It's been a couple of days now with the new gpu but I've started to notice some problems.. I would get driver crashes, green screens when i'm watching streams off twitch.tv, and fps drop on games (Warface for example).

Any solution? I'm running on 350 watt btw. I was told I didn't need a psu upgrade if I decided to switch to this gpu.
 
While I will agree cooler master makes a good power supply and I have one thats 6 years old rated at 650 watts I would still get the seasonic today and yesterday if I have known better but knock on wood its still going to no pun intended its legit.
