Processor: Intel Core 2 Duo processors power the new MacBook. With speeds that reach up to 2.4GHz, browsing the web, emailing and other everyday tasks can be done in a breeze. If you’re into more processor-intensive applications, no worries, the MacBook has enough horsepower to let you run these applications with ease.
Hard Drive: Plan your MacBook hardware upgrades according to your memory needs. If you plan to use your MacBook primarily for word processing, and web browsing, then hard drive space will be of little concern as the new MacBook comes with a 250GB Serial ATA hard drive. If you're looking to store pictures, videos, music and other media heavy files, look for the bigger 320GB. Should you need space above and beyond the capacity of your hard drive, fret not; you can always buy an external hard drive for extra storage options. Currently, the MacBook comes with up to a 500GB Hard drive upgrade.
Memory: The performance of your MacBook in running applications, programs and games highly depends on its RAM. The higher your memory, the more programs you can run at the same time, and the more intensive applications run smoother. MacBook’s memory comes with a standard of 2GB (two 1GB SO-DIMMs) of 1066MHz DDR3 RAM but supports up to 4GB (two SO-DIMM slots) of RAM. MacBook hardware upgrades can get a lot of mileage from upgrading memory as it is cheap and has a great impact on system performance.
Graphics: If you’re looking for a notebook that can keep up while you play Call of Duty 4 or Doom 3 all day, rest assured that the MacBook fits the bill. Equipped with the new NVIDIA GeForce 320M graphics processor (80 percent better than the previous generation), the MacBook now delivers smoother and more responsive action for graphics-intensive games.
