75C is a safe/normal temperature for graphics cards. It could be better, but it runs the same at 75C as it does at 60C so I wouldn't worry about it(unless you plan to overclock).
My GTX 760 runs at 76C usually under load with the EVGA ACX 2.0 cooler on it. I have a small overclock on it though. I believe it still sat in the low to mid 70's before I overclocked it though.
