I'm debating on whether -- when they are upgraded -- to get the top of the line 15 inch macbook pro or the top of the line macbook air. I'm going to college in 2011 and I do hope to do a tad bit of gaming during part of my free time. I currently have a early 2008 Macbook Pro with a 2.4 ghz intel core 2 duo processor and 2 gb of ram along with a 256 nvidia 8600m GT graphics card and a 5400 rpm 200 gb hdd. I can run call of duty 4 at almost maximum settings with little to no tearing, blurring, or lag during both single player and online play. Would the macbook air be faster than my current system? Could I run games like left for dead 2 or the steam ww2 game (i forgot what it's called) at medium to good quality? How about with the current macbook air? Would the macbook pro be a better choice? I absolutely love the size of the macbook air and the appeal of steam is that I don't need to use a disk to run the games (which would be good on a macbook air). Thank you!
