I'm buying a new laptop, and have the choice between these two models from HP. Can someone please help me choose. This is not my main workstation, but rather a travel pc, but it will be used with solidworks and simulation among other things. The Elitebook is around 350$ more than the Probook.

Alternative 1:

Model: HP Probook 6550b

Screen: 15,6”

Prosessor: Intel Core i5 520M / 2.4 GHz ( 2.93 GHz )

Memory: 4GB

Harddrive: 320GB

Graphic card: Intel HD Graphics

3G: yes

Alternative 2:

Model: HP EliteBook 8440p

Screen: 14”

Prosessor: Intel Core i7 620M / 2.66 GHz ( 3.33 GHz )

Memory: 4GB

Harddrive: 320GB

Graphic card: NVIDIA NVS 3100M

3G: No

I can also upgrade 8gb ram on both models for 250$
