Would this be a good mid-level computer for gaming?

Lenovo G505s 15.6" Laptop

AMD A10-5750M Quad Core APU, 2.5GHz processor
8GB DDR3-1600 MHz RAM
1TB HDD, 5400 RPM hard drive
15.6" HD LED backlight widescreen display

Are these specs decent for games such as Skyrim or ARR: FFXIV?

Yes, but you're looking for the GPU specs mainly as I just searched them and it's running a Graphics CoprocessorATI Radeon HD 8650G It'll be very decent for mid level gaming.
