I had no problems with running my games, and most important one - Counter Strike Source runs same as it does in XP, so I'm happy.
I also should note that my Sony Vaio SZ-370 laptop has only a 64MB Video Card (Nvidia 7400 Go) but everything - including full Aero experience and high-end games - run without a hitch! So, those reviews telling you that you HAVE to have 128MB graphics card to enjoy all of the Vista experience - are not true... 64MB does a really good job, and 128MB and more will just do even a better job in your gaming experience.
