These are all correct. The main thing that makes a difference is going to be that the Laptop has either the ATI Radeon 9000 chip or one of the NVIDIA chips. I would look for a laptop that has at least 64mb of DDR video memory, but you could get away with 32mb.
I think the best would be the Dell Inspiron 8500 for the price.
