What you want to get depends on how much data you want to visualize at one time.  If you are only looking at small molecules, almost any laptop will do.  If you are looking at bigger systems, then a laptop might not be good enough. I don't think you can buy one anymore, but the best laptops were those with NVIDIA Quadro (not NVS) graphics and a 3D stereo display (120Mhz, 3D glasses).  Chimera needs workstation graphics (NVIDIA Quadro or AMD FirePro/FireGL), to support 3D stereo viewing. For most people, any decent gaming laptop will do.  My order of optimization would start the the graphics.  Stay away from Intel graphics, go for NVIDIA or AMD graphics -- the higher end, the better; and the more dedicated graphics memory, the better.  Next, pick a fast CPU -- some parts of Chimera are single-core CPU bound.  Next, more memory is better, 4GB for small data, 8/16/32 for larger data.  Screen resolution isn't that important -- higher screen resolutions need better graphics to keep the 3D interactive, and you can always use F11 to switch into and out of fullscreen graphics.  And a SSD is very, very nice, it will improve the overall responsiveness of the computer, but is not critical for Chimera. But some people are happy with laptops that have Intel graphics. Again, it depends on how much data you want to visualize at one time.  Ideally, you would demo the laptop you want to buy with your data before buying it.  Next best thing would be to try out your friend's laptop. You can see user-submitted Chimera benchmark results at http://plato.cgl.ucsf.edu/trac/chimera/wiki/benchmarks.  There aren't many results for recent graphics cards.  Please submit the results for the system you end up getting.     Best of luck,     Greg On 2/18/19 7:43 AM, p.tapi@alice.it wrote:

May you answer me  regarding the *main laptop features* ( CPU type, speed, RAM, SSD, screen resolution, etc ) *you recommended* ? What you suggestions ?

Thanks in advance Regards
