For following type of Usage

What would you suggest

DELL M4800 or MSI WS60- 20J

Using Sw 2012

Med size assembly ( lot of fasteners but not much rendering requirement or high level surface modeling)

International Warranty is important ( Australia/ Singapore/ India/ USA)

DELL = AUD 3440 ( On site 3 years)

MSI = #3499 ( Return to Base 3 yrs n+ VAR is offering replacement if Laptop is going to factory for a period)

Need to take urgent decision!

Thanks
