Hello fellow Mac users! I've been a long time reader of these forums and I finally decided to make a post since I'm about to make the switch (I'm buying both an iMac and a MBP!) My question in particular was about the MBP. I've done a lot of reading and for quite some time I knew I was going to get the base version 15" MBP. I wasn't planning on gaming at all, so the lack of a dedicated graphics card was a non issue. But... I recently saw Starcraft II and found that it will be releasing sometime this summer, and I was just wondering if the 9400m can handle games like that on medium without lagging? Should I bump up to the 256 or the 512 over this? I know this will be hard to answer because the game hasn't even been released. If you could help that would be great. If you can't thanks anyways. Can't wait to switch!
