most of your Motherboards nowadays DONT include onboard graphics anymore. That's a thing of the past. Nearly all processors nowadays have integrated GPU's on the processor die. The ones that don't are simply expected to be put together with a dedicated GPU, like some of the FX-series lineup.
all this is null and void if you're running very old hardware though, like the pentiums of old. I would hope you aren't subjecting that 650ti to such a pitiful bottleneck as an old Pentium 4 though.
