I'm looking to buy a mac, but I have a computer that I use for load-intensive apps and gaming (so far.) I'm wanting to get into macs as a primary system, but I want to make sure I like them before I spend 2,000+ on a mac! My questions is whether or not this is a good buy! Please post your opinion, and your reasoning!
