I'm considering getting a new laptop soon (probably once Windows 7 comes out), and I'm looking at the Lenovo T400 series, which has the ATI Mobility Radeon 3470 graphics card. Everything else is a direct upgrade, however my current laptop has the ATI Mobility FireGL V5250.
I know that my current card has 512MB of RAM built into it, while the Radeon that I'd get only has 256MB, but I don't do a lot of hard-core gaming or graphics work. However, I do occassionally game and watch videos on my laptop, along with using my laptop as a TV through an external TV tuner. What should I know about the ATI Mobility Radeon 3470 before I purchase a laptop with one?
