Just ordered this:
Alienware M15x Special Edition ? Nebula Red, IntelŽ Core? i7-720QM Quad Core Processor 1.6GHz (2.8GHz Turbo Mode, 6MB Cache), 6GB DDR3 at 1333MHz, 15.6-inch WideFHD 1920x1080 (1080p) WLED, 1GB NVIDIAŽ GeForceŽ GTX 260M, 256GB Solid State Drive
I'm replacing an almost 2 year old m15x with 2.6 core 2 duo and 4gb of ram.
I used the m15x w/ 2.6 core 2 duo for almost a year as my only pc. Bought an Alienware desktop with i7 920 2.67 and 6GB of ram, mainly to run 2 monitors again. Apart from having 2gb more ram and 7200 RPM drives in RAID 0 that was the main difference between the two. (Not counting video cards ;))
I'll just say the 2.67 i7 blows away the 2.6 core 2 duo. This desktop makes my old laptop seem like a total pos... when it's actually a great pc. Both are running Window 7 Ultimate 64 bit.
When I was reading the reviews of the mobile i7, they showed all sorts of benchmarks where even the slowest 1.6 mobile i7 blew away even the extreme core 2 duo mobile chip.
I'm really most interested to see how the 256gb solid state hard drive is. If it's as good as people are saying, I'll probably buy one for the desktop and move the 2 500gb drives to storage duty
I'll get the M15x in a few day, I'll let you know what I think :D
