G2 should run very well on your machine. You might have to press 'Escape' early on in the session; I think this is because the cache hasn't yet stored some of the commands.

As a general rule, it's always worthwhile making sure you have all the latest drivers, especially for your chipset (which should be an 850, with a machine like that).

Try visiting both your machine manufacturer's and Microsoft's website for any updated drivers they might have. Also, make sure you have the latest service packs downloaded and installed. This is even more important with newer machines.
