I really was looking for a desktop replacement, but I was told by management that DS will not be offering X17E laptops due to the chassis manufacturer, Clevo, having run into issues with the hardware. So at the moment, no X17E laptops can be purchased. 

So I was looking into the x17 and at this config..

Chassis Model: Digital Storm x17 Laptop (Model: 9170)
Display: 17.3 Inch (16:9) (Resolution: 1920 x 1080) (Glossy Surface) LED-Backlit Display

Thermal Compound: Premium IC Diamond CPU and GPU Thermal Compound (Reduces Thermal & Laptop Noise)

Video Card(s): NVIDIA GeForce GTX 675M 2GB with NVIDIA Optimus Technology
Windows OS: Microsoft Windows 7 Home Premium (64-Bit Edition)

80% of the time it will be sitting on my desk connected to a docking station... Toshiba PA3927U-1PRP Dynadock U3.0 Universal USB Connect Docking Station and the Monitor I have is the Dell 24 U2410

Being a "mobile" GPU would the GTX 675 be able to handle 1920 x 1200 on the Dell 24 U2410 ?

My DS desktop is almost 3 years old... GTX 480, i7 930 2.8GHz, MB EVGA X58 LE and 160 SSD   In your best guess..... how much of a performance increase should I expect with the laptop compared with the older desktop ??   slight/moderate/high ??

The games I play now are WoW and SWTOR and my desktop destroys them... although SWTOR runs my GTX 480 very hot.. hehe   Future games I'm looking to play are GW2 and Daiblo 3... I'm sure the this Laptop could handle them, but I would just like to be sure.

Thanks for your time and answers
