your IGP can handle any general use and light gaming, but if you put 730 with 6500, that was not a good idea. Try to get a better card, 730 is not a good card, rather than a mid-end budget card. An IGP won't Hurt any CPU or ANYTHING else, unlike an Onboard Graphics chip, IGP is embedded on a CPU itself.
My Advise; save your money for a better card, a 6500 deserves better than 730 In My Opinion, a decent GPU like a R9 380 or GTX 970 and budget-alternative RX 460 is not a bad choice even for nowadays gaming. But you can always use IGP anytime, a GTX 1060 also a good choice. Use your IGP for a while, when saving your money for a better video card on the market.
