You would have to know what kind of work you are going to have to do on this machine. In order of magnitude, a real portable station (screen and graphics card worthy of the name) capable of supporting a strong 3D model, it's more like 2-3k€ that you have to count.
I found it as a condition so I don't really understand that nothing is okay thank you for your answers
Before you install SOLIDWORKS Visualize and SOLIDWORKS Visualize Boost, you must have the following prerequisites for each computer :
A SOLIDWORKS Visualize serial number
A SOLIDWORKS Visualize Boost serial number
Each computer running SOLIDWORKS Visualize or SOLIDWORKS Visualize Boost must meet the following requirements:
Windows® 7 or higher (64-bit )
Dual-core processor; quadruple core recommended
8 GB RAM ; 16 GB recommended
2 GB of disk space; 5 GB recommended
2 GB or more of graphics card RAM; 4 GB recommended
NVIDIA® graphics card: NVIDIA Quadro®/NVIDIA GeForce®/Tesla™ with at least one NVIDIA Kepler™ chip; Dual GPU configuration with at least NVIDIA Maxwell™ cards for the best experience
NVIDIA driver version 385.41 (or later) recommended
NVIDIA driver that supports CUDA® 9.0 or later required
Connecting HDR Light Studio HDR Light Studio v5.3.3 or later, except v5.4
4 GB or more of video memory required for the Denoiser feature
If non-NVIDIA graphics cards are installed, SOLIDWORKS Visualize defaults to the CPU, not those cards, for GPU acceleration. In addition, NVIDIA cards based on the Fermi™ architecture no longer support GPU acceleration.
It really depends on the type of parts and assemblies created and handled...
I run with a Dell Latitude 5580 intel core i7 7820HQ at 2.9 Ghz, 16 GB Ram and an integrated intel 630 graphics card ... but I never do surface, I have assemblies of 600 to 800 parts maximum... To spice things up a bit, I work under Epdm and often telecommuting (by VPN) ... And I never have any problems. On the other hand, it is set up with great care...
