Okay, so I am a total noob when it comes to Mac. I am in the market for a new Mac and my budget is roughly $1500... http://www.amazon.com/Apple-MB324LL...ref=sr_1_3?ie=UTF8&s=pc&qid=1228526191&sr=1-3 and http://www.amazon.com/Apple-MB133LL...ref=sr_1_3?ie=UTF8&s=pc&qid=1228526294&sr=1-3 are the two that I have seem to have narrowed it down. Both have similar specs but the main difference is the GFX card. I will be using the computer for some gaming (mainly Counter-Strike: Source), photo editing and some video editing. I plan on boosting both up to 4GB of ram. Which would better suit my needs?
