I've been looking at the reviews for the new MacBook and MacBook Pro's that were just released last week.
The graphics performance is definitely a huge improvement over the existing Macbooks. It actually turns out that in some games the new MacBook actually out performs my existing iMac. This has really got me thinking on whether or not I need the extra video card, especially since you can't run it in SLI mode.
Right now the only game I really play regularly is WoW, and if the new MacBook can run that well, it might be just what I need.
I do believe it may be time to make a visit to the Apple store for a little 'hands on' with the new MacBooks.
