Original Apple MacBook Pro 17" 2.6GHZ 4GB RAM 500GB Brand New MB766LL/A

Intel Core 2 Duo Processor
Experience improved energy efficiency, expanded wireless connectivity, and amazing battery life with the 45nm Penryn series Intel Core 2 Duo T9500 processor, which has a 2.60 GHz processor speed, super-fast 800 MHz front-side bus (FSB), and a super-sized 6 MB L2 cache. (An L2, or secondary, cache temporarily stores data; and a larger L2 cache can help speed up your system's performance. The FSB carries data between the CPU and RAM, and a faster front-side bus will deliver better overall performance.)
The new hafnium-infused circuitry--which reduces electrical current leakage in transistors--conserves even more energy, giving you more time away from the wall outlet. With a whopping 6 MB of shared L2 cache, data and instructions can be kept close to the two processor cores, greatly increasing performance and allowing the entire system to work more efficiently. And, because the processor cores share the L2 cache, either can use the entire amount if the other happens to be idle.
Your hands have room to spread out on the full-size keyboard with crisp, responsive keys.
Hard Drive and Memory
The 500 GB (upgraded from 250GB) Serial-ATA (SATA) hard drive quickens the pace with a higher speed transfer of data--akin to FireWire and USB 2.0. The 4GB
Wireless Connectivity
The built-in 802.11n wireless networking provides up to five times the performance and twice the range of 802.11g, but it's also backward-compatible with 802.11a/b/g routers, enabling you to communicate with the a wide variety of Wi-Fi resources. It works seamlessly with the new AirPort Extreme with 802.11n. Use the built-in Bluetooth wireless technology to connect to your PDA or cell phone, synchronize addresses, or download pictures from your cell phone. You can also use a wireless headset for iChat audio chats and VoIP calls as well as quickly share files with a colleague.
Display and Graphics
The 17-inch widescreen TFT display offers a native resolution of 1920X1200 pixels and an antiglare widescreen display that's perfect for color-minded professionals. It's also better for the environment, thanks to its new mercury-free display.
Video and graphics are powered by the NVIDIA GeForce 8600M GT card, which is boosted by 512 MB of GDDR3 SDRAM. GDDR3 (Graphics Double Data Rate, version 3) is a graphics card-specific memory technology that's better able to deliver fluid frame rates for even the most advanced games and applications. The GeForce 8600M GT brings a new level of realism to the MacBook Pro with its 16-lane PCI Express architecture, 16x full screen anti-aliasing, 128-bit High Dynamic Range rendering, and a texture fill rate of up to 8.2 billion per second.
Video Conferencing with Built-in iSight
Artfully placed in the display bezel is an iSight camera, which enables easy video conferencing as well as allows you to snap pictures of yourself and create video podcasts. Using the iChat AV application, video conferencing is integrated into your iChat buddy list, so initiating a video conference is a breeze. iChat also lets you hold audio chats with up to 10 people and provides high-quality audio compression and full-duplex sound so conversation can flow naturally. For video podcasting, you can record a short clip using the iSight camera, then use iWeb to create a video blog entry or post your GarageBand-recorded podcast.
