Whoa, that's bad, you should really RMA yours.
Your PC should be running at least 20 degrees cooler, gain 100% more FPS and download speed increased by 500%, and for the price you pay for these gains, it's an insane deal.
Oh man, OcUK can I RMA my sticker? I'm not seeing performance increases like Idar is.
Can you run some diagnostics on it and see if it's faulty?
