I don't really trust things like game booster etc for CPU temperatures. either read it straight from BIOS, or use CPU-Z, Hardware-monitor, or some other software developed for this type of thing.
other than that, 63C on load is perfectly fine. I've run my i5 2500k upto 75C or so and it's less heat tolerant than your CPU. I think you're looking at a long and happy life with your computer (at least once you get your GPU back)
