It will run most games fine but don't expect that u can run high graphics game smoothly at Max settings.
Adreno 305 in the 730 is widely used in a lot of low to mid end handsets (even my 620) and it delivers a decent experience for the price range but it can't compete with GPUs like Mali 450MP4 or Power VR sgx 544 mp2 which are available on some similarly priced android phones.
