Wich Macbook Pro should I get?

Hello all,,,

I am mac user for 4 years now, and at the moment i own 2007 macbook with 2.4gHz intel core 2 duo procesror, with 4gb ram, and 250gb hdd 7200rpg...

So I am looking to buy new macbook,,,

I would love to stay on 13" screen, but what bothers me is graphic inside 13" one...

So my question is is graphic in 15" much better that one in 13",,,



Intel HD Graphics 3000, in 13" ($1,098.00)

AMD Radeon HD 6750M with 512MB GDDR5, in 15" ($1,698.00)

having in mind that I would prefer to stay on 13", is this 15" worth that 500$?



Basicly I need comp for audio editing, and video editing, booth on home level, I am self learned amateur in booth , and sometimes love to play World of Warcraft...

Now, video and audio editing runs smoothly on my machine, but WoW have lot of FPS problem...



So please advice me what to do...
MacBook, Mac OS X (10.7.2)

If WoW is the most intense game you'll be playing, the HD3000 handles that quite well. I've got a few multi-hour sessions on my MBA that's only got a 1.8Ghz dual core i7 with the HD3000.

Of course the 15" would have better graphics than the 13".
If i had the money i would choose the 15" because it will be better in the long run, but if you don't do any heavy (professional) video editing or gaming. I'd say the 13" will do just fine. ;D
