Okay i'm a PC guy. But on a slightly unrelated note how does minecraft handle processor power. I will be installing an 8-core soon. Just asking because I've heard that minecraft handles additional cores badly.
edit: i may as well throw my 2 cents in on the PC/Mac discussion. I personally hate how apple handles upgrading. they make it hard to say the least if you want a better gpu you buy a new mac. there is one product as of now i could see myself using, and that's their retina display. It is worth the extra money. everything else i have replaced. Besides zune is so much better than iTunes.
