Is the nVidia GeForce GT 745M a good graphics card?

I have this graphics card, which came pre-installed (obviously) in my laptop. I was just wondering what the quality of it was and if there are any ways of getting it to perform better than on the default settings. Also, I was wondering if this graphics card would allow me to play games like League of Legends, RuneScape, Skyrim, Outlast, Minecraft, etc. Etc…
It may seem like a nooby question, but answers are greatly appreciated as I'm a novice when it comes to graphics cards!

To find out if your system meets the requirements to play those games, go to the Systems Requirements Lab web site, also known as "Can You Run It?"

It's not bad, mid range as far as laptop graphics cards. It'll let you play most games using the mid to upper in-game settings to get frame rates of 40+ fps, though you may need to reduce the resolution with some games.
