Hello, I have a Fall 2006 MacBook Pro 2.33GHz Core 2 Duo with 2 gigs of ram. Part 1 I think that I am going to upgrade my hard drive to a 500gig 7200 rpm hard drive because mine is so full I have to always rely on my external. That being said are there any recommendations on a particular hd, looking through the forums I spotted these two drives, but I also know nothing of the websites reputations http://www.powerbookmedic.com/500GB-7200RPM-MacBook-Pro-Hard-Drive-Upgrade-p-17296.html and http://eshop.macsales.com/item/Seagate/DIYST95007U2/ Any other drives I should check out? Part 2 I work quite a bit in photoshop and do some side gaming, starcraft 2 in bootcamp ect. I was looking into updating my RAM but it appears as though my system only supports 3 gigs of RAM, so I would lose some of the benefits of having a paired ram config. However, i was reading on a macrumor page about ram and it seemed as though it would be alright to put in a paired 4 gig setup. Is this true or will it screw something up?? If there are any other good ideas for how to get a little more mileage out of this computer, i would be very appreciative. Thanks!!
