What kind of laptop would suit this best?

Things I will be doing:
-Playing video games
-Video editing
-Using the Internet
-Skyping while playing video games
-Recording gameplay (possibly with Fraps) (Recording MineCraft, mainly)

Things I want:
-No lag when playing (especially while recording)
-Windows 7 Operating System (I hate Windows 8)

I was thinking a Macbook might be good. Please recommend some gaming LAPTOPS! Thanks!

P.S. No laptops and my price limit is $2,500
