Vista, we are told, is much more graphics focused. There is a fundamental shift from bitmap images to vector graphics, much more focus on shifting workload from the CPU to the GPU, and will require a serious display card to be included in the machine. A 128 megabyte display card will be good, and a 256 megabyte or better display card will be ideal.
The graphics capability will need to be accompanied by rather large amounts of system memory. Half a gigabyte of system RAM will be usable for 32-bit computing, although 1 gigabyte would be much better. Double that amount is needed for 64-bit computing. DDR3 RAM will be best for unlocking the speed and power of Vista.
