Vista gives me a rating of 2.0 because of my Radeon X300, which as 64MB of memory. I run my computer with 512MB of system memory. These statistics fall short of minimum requirements for the premium-ready computers, but my notebook is able to run Aero (with Flip3D) flawlessly. What’s interesting is that 64MB of system memory is being used for video memory to bring up my total to 128MB. Of course, Vista is not as snappy as XP used to be on my computer, but it’s responsive enough to be productive for everyday use.
