So i have a http://www.newegg.com/Product/Product.aspx?Item=N82E16817341018 and i have a EVGA Geforce GTX 560 Ti 448 classified that i bought less than 6 months ago. I am using EVGA Precision and EVGA OC Scanner X to increase the speeds, but if i were to increase the voltage would my PSU be able to handle that? I am getting Core 896Mhz, Shader 1792, and Memory 1950 right now without having increased the voltage to the GPU, just the clocks. My card gets to around 84ºC at the most when under heavy load, mainly just Shogun 2. So if i were to up my voltage would that lower my temp under heavy stress like Shogun, and also allow me to increase my clock speeds? If my PSU isn't sufficient i was thinking of getting this one http://www.newegg.com/Product/Product.aspx?Item=N82E16817171049, but i'm just going off that fact that it is 300watts more than mine and has a 5star rating on Newegg. I am not really sure what i should be looking for there. I just want to be safe if i increase the volts to my GPU. Also, I can't go over 225 dollars either if i need to upgrade my PSU. A thousand thanks to whomever can help me.
