Can my pc run rainbow six vegas 2?

I wouldn't bet on it running even on the lowest settings,but you could look into building a computer for gaming which might cost you $400 if you wanted to cheap out,but i wouldnt buy a new video card cause your system would bottleneck it and you wouldnt get all the performance.If you do want to build a new computer which is always better than buying one and it is easy to put together,look on youtube for videos on how to build a computer or a guide somewhere but almost everything in a computer is plug in play,and also go to newegg dot come cause they sell the cheapest parts and ship fast and lots of people love them
