it should be fine. anyway, for your OC, dont just add 200MHz and call it a day, fine tune it for the best possible and stable performance.
What do you think I should do with the OC now? Well... at least that made my paranoia go away.
I ran alley benchmark for nearly 2 hours and the GPU didn't go over 68 degrees and I ran Sniper Elite 2 benchmark as well a couple of times, the OC increased average fps by 11-12.
