Been tossing up between the two now for over a few weeks and i thought i'd throw the question out there to gauge what other peoples opinions are.
Firstly, the biggest use i'd have for this would be audio related... aka, music production and using it to play live. Very slight gaming, only world of Warcraft really. Battery life isn't important as it will be plugged in, either is weight. Screen resolution doesn't matter that much as i wont be using it to watch movies. Being able to handle all the audio demands live and without stuttering is paramount...
The specs are a little different here in aus.. so heres a basic run down of the two systems:-
Studio 17 :- $1599 Aus (No Coupons)
Intel® Core™ i7-620M (2.66GHz, 4 Threads, turbo boost up to 3.33GHz, 4M cache)
8GB Dual-channel 1066MHz DDR3 SDRAM (2 x 4GB)
1.28TB 5400RPM SATA Hard Drive (2x640GB)
17.3” High Definition+ WLED (1600x900) Display with TrueLife™
1GB ATI Mobility Radeon™ HD 5650
Studio XPS 15:- $1499 AUS (no coupons)
Intel® Core™ i7-740QM (1.73GHz, 4Core/8Threads, turbo boost up to 2.93Ghz, 6M cache)
6GB 1333MHz DDR3 SDRAM (1 x 2GB + 1 x 4GB)
640GB 7200RPM Hard Drive
15.6 HD (1366x768) WLED display with TrueLife™
2GB NVIDIA® GeForce® GT 435M graphics
Sorry if this is in the wrong place, as i'm not to sure where to put it.
