So I overclocked my GTX 750Ti a few days ago the memory up to 5800mhz from 5500mhz and the core to 1268mhz from 1163. Before the oc unigine valley was running at 73 degrees celsius max but now with the overclock it runs at 77 degrees celsius max. Is 77 degrees celsius normal for an overclocked GTX 750Ti? Should I be worried? Here's my card http://www.techpowerup.com/gpudb/b2799/gainward-gtx-750-ti.html
