I've got a 2009 Mini that's in my signature at the moment. I'm thinking of upgrading to the higher end of the new Mini's. I was wondering if anyone had opinions on the performance difference between the Nvidia 9400M in my old Mini and the ATM Radeon 6630M in the new one. They both have 256MB of VRAM. On a related note is there a significant performance increase between the 2.53 Core 2Duo and the 2.7 Core i7. Also is there any significant difference between the 5400RPM 320GB HD in the old one and a 7200RPM HD in the new one other then the obvious extra capacity. To sum up I'm trying to determine the overall performance between the two Mini's. I mostly use it for email, internet, storing my iTunes library plus some games. I do have games consoles so the games part is not significant but I would like to play games like Portal 2 and the upcoming Diablo III. I might also dabble in WOW. I don't use it for any multi media or graphic design applications. Also anyone have any idea the typical value of the old one if I sell it in particular here in the UK. I would appreciate any useful insight into this. Thanks.
