I am going to buy meself a MBP 15 soon. i use to thinking of the fastest i7 one. After read several posts here, i feel like i5 2.4G might enough for me. The only concern is about the video ram. I understand the MBP is not design for gaming, but unfortunately i have to play some game on that. I will also mostly go with the Hi Res screen as well. could any one post some comparing link between GT 330 256 AND 512 both under Hi res. i find some gaming test either under standard res, or hi res with i7. rarely find some gaming test on i5 with hi res. thank you.
