Hi, I'm looking forward to buy a new Macbook pro and I'd like to buy the 15" inch 2.0 GHz (quad-core Intel Core i7, 4Gb RAM, Intel HD Graphics 3000 + AMD Radeon HD 6490M with 256MB GDDR5). However, as a gamer, I'd like to be able to play Call Of Duty : Black Ops (this is the game I play the most, so I'll give that one as an example) on my computer. So, would I be able to play it? If not, would I be able to play it on the 15" 2.2GHz version (with Intel HD Graphics 3000 + AMD Radeon HD 6750M with 1GB GDDR5)? If not again, what is the highest demanding game that I could play on the first computer. All this considered I would run Windows on it. Thanks And is it worth it to buy the 2.2GHz instead of the 2.0GHz or is there not that much of a difference?
