What is the value of the Nvidia GeForce GT 635M?

Hello, how good is the Nvidia GeForce GT 635M graphics card? Is it strong? Does it make games run more smoothly? Does it allow me to run Unity3D or UDK smoothly, with the Intel i7 3610QM quad-core 2.4 GHz/3.4 GHz Turbo Boost and also 8 GB of RAM, and finally a 1000 GB (1 TB) 7200 RPM hard drive, one of the only ones with 7200? It runs on Windows 8. Thank you.

Configuration: iPhone / Safari 6.0
