Just setup a 2008 Lenovo t430 laptop with windows 7 (going to use it to check website rendering as I'm fed up of booting into Parellels and it slowing my entire machine to a crawl) Anyway, I'm wondering why the hell this crappy old Lenovo with an old ATI 3400 graphic card blows away my Unibody 2008 MBP 8 gigs of ram and 9600GT video card when viewing Big Buck Bunny in 1080p! The Lenovo is just ticking over at 26% cpu usage BUT my poor MBP is hitting 80% or more. I have the latest versions of flash player on both machines and used Chrome too! This is the video I'm watching http://www.youtube.com/watch?v=XSGBVzeBUbk Seems like Adobe is purposely screwing with something here? The video also loaded a lot quicker on window7 than my MBP ???
