Is my hardware supported

I'm a beginner and I plan on switching to Linux. For the last month I've been trying out distros on a VirtualBox and I've decided to go with Linux Mint Xfce. I'm still kinda scared to migrate because I don't know if it'll all work, my main concern is if my graphics card is supported. Here's my rig:

• Intel Core i3 530 2.93GHz
• 4GB Ram DDR3
• Nvidia Geforce GTS 250
• 2 TB hard drive

Will my graphics card be supported? It is currently on driver version 342.01. Is there anything else that might not be supported? Thanks in advance.

P.S I know my internet will work, I have an ethernet cable.
