Will the game run well for me?

[just_another_man]

AMD Anthlon II X2 250 Processor 3.00 GHz
4.00 GB RAM
Windows 7 64 bit
Realtek High Definition Audio
530 GB of free disk space
ATI Radeon HD 4200 video card.

My video card is what I am most worried about. It has 1.9 GB Video RAM, and is DirectX 10.1 compliant. Also, Internal DAC(400MHz). I am guessing it is good enough, however I'd like to know for sure before I buy the game.

I've never had a PC game before, only really played console games. So will Cliffs of Dover run on my PC?
