Minimum requirements for a tethered laptop

I'm exploring my options for portrait sessions using tethered shooting. Never did it before. Camera is Fuji. Tethering software, unless there is a much better option without changing from Lightroom/Photoshop, will be X Acquire.

 

I am hoping I can utilize a minimal spec'd laptop since all I want to do is use the laptop to display images as they are shot for the benefit of myself and the client to view. Since processing is not really going to be a factor, just image display, via Lightroom, what level of processor / laptop can I get away with? Am I thinking correctly?

 

Also, can you direct tethering software to save the images to the SD card and also a destination folder on the desktop or only the desktop?

 

Thanks

You may have already found the answer to your question (sorry, I only joined today). LR allows you to save images directly to the computer in the folder of your choice - which is what I do. Don't know how long the Fuji cable is but the Nikon USB cable is far too short and I've had on/off connection problems when using a USB extension. Best bet is to invest in a powered USB cable. Pretty expensive (mine cost €90) but it gives a consistently good connection.
