[Moutooz]

I currently have a fujitsu AH530 and I might be getting the MSI GX720. The specs for the fujitsu are:
Processor:

Multi-Core Technology: Dual-Core
64-bit Computing: Yes
Chipset Type: Mobile Intel HM55 Express
Cache Memory

RAM
Installed Size: 4.0 GB

Configuration Features: 2 x 2 GB

Storage
Floppy Drive: None
Hard Drive: 500.0 GB – Serial ATA-150 – 5400.0 rpm
Storage Removable: None
Hard drive type: Portable

And the specs for the MSI GX720 are:
• The latest Intel® Centrino® 2 Processor Technology
• Genuine Windows Vista® Home Premium
• 17" TFT-LCD Widescreen Display
• Exclusive Turbo Drive Engine Technology
• Exclusive ECO Engine Power Management System
• The Combination of Aluminum and Metallic Threads in Body Design
• The nVIDIA Geforce 9600M GT 3D Graphic Card with DDR3 512 MB VRAM
• Theater Class 5 Speakers

So im confused whether to keep my fujitsu or to switch to this MSI laptop, according to these specs which one is better? I'm 17 so I use the laptop for gaming purposes at most.
Thanks x
