its still a decent laptop, but it is pretty out of date now if you are talking about newer triple a titles. since its on your mind, its probably time to upgrade. something must have made you think about it. a newer laptop with a 970m for example will probably give you a minimum of 5x improvement.
The CPU itself is still considered powerful. The AMD GPU is a different story.... an Intel HD 5500 in Haswell CPUs is a bit more powerful than the Radeon HD 7630m. It is more powerful than an Intel HD 4400 in Broadwell CPUs though. In other words it's pretty weak compared to modern dedicated graphics.
You can still play some games with low settings but it would be best not to have high expectations.
