if i were to purchase a computer i think the best choice would be the:

M17 17-inch CrossFireX™ / Core™2 Quad from alien ware

it is made mostly for gaming but has a lot of other features that make it an overall success
some features include

• Intel® Core™2 Extreme Quad
• ATI CrossFireX™ Dual Graphics
• 4GB 1066MHz DDR3 Memory
• 1TB Hard Drive Capacity
• Extreme High Def Video and Audio
• Full-size Illuminated Keyboard

from all this information what you can deduct is its 1 terabyte memory! which is unheard of and its 1066 mega hertz of processing which makes it really fast. It has 1 terabyte of memory!! which i have not even heard of in a computer, especially a laptop. 4 gigabytes of ram and hi-def sound and video for movies and games. The best part is that its only 1400 which is a little for this high speed computer. this thing is so fast that it does what you want, before you even know you want it.
