I want a xbox 360 to play forza 3 on.
Which is the best one to buy elite or pro and what size hd?

aren't they all the same except for larger HDD's?

Unless you want to store loads of music on it then the 20gb hard drive is more than enough. Mines not full after 4 yrs use. Elite is a waste of money in my opinion but i'm sure someone else will disagree.
Forza 3 is ace btw.

Elite has HDMI and PRO doesn't?

Just get the elite ltd edition with Forza included.

get the elite with a 20G hard drive, it'll be all you need for playing games on. My forza 3 is already on it's way[1]

[1] sorry, I mean stuck in a royal mail sorting office somewhere, ignored and unloved.

Larger Hard Drives do make sense for some people – not just for music, but because you can install the actual game onto the HD rather than run straight from the DVD. Cuts down on noise significantly and speeds up load times. I've got a 60gb HD and along with a few demos and installed games it didn't take long to fill it up. Obviously you can delete stuff you don't want though…

as mentioned above, get a elite bundle, HMV are doing a great one, £197 for elite, Forza 3 and fifa 10…

if you don't like fifa, trade it in… you'll probably get about £20 for it.

What is the big different between Forza 2 and 3?
