I have a 2.33Ghz Core2Duo 17" Macbook pro and I am considering upgrading the memory and hard drive. The current HD is a 160GB 5400RPM and I would like to upgrade to a 320GB 7200RPM. I think that I will also upgrade the 2x 1GB 667 sticks to 2x 2GB 667 for a total of 4GB of RAM. What is the best deal that I can get on these components? If you could provide some links, that would be great. I just want to make sure that they are compatable and reliable, but most of all, cheap. Also, what sort of performance increases will I seem both in daily use (web browsing, word processing, light photoshop) and gaming with these upgrades? Thank you.
