AMD_POTATO :
I would get an i7 7700 and a GTX 1080 those should work well for your use case
Thanks AMD_POTATO for those recommendations! I was indeed looking at the i7-7700, but then the search got more complicated, as there are different types of 1080s, whose difference I don't understand well, and a myriad options for motherboard, amount and type of RAM and size and type of SSD, Maybe a Gigabyte Gaming 7, 2x8GB 3000 RAM and an 800GB SSD Intel 750 (the new faster ones)? Any advice on specific capacities or models for these? I mostly get confused between the different sockets each MoBo has, regarding which ones better suit me or future-proofs my rig; whether the RAM speed, amount and model really matters, etc.
And my other concern is how to drive multiple panels: 3 for scenery, 2 for instruments and one touch screen for buttons; whether the one 1080 would handle all that, or whether to use it only for the 3 scenery monitors and use my older graphics card to drive the 2 instrument panels and the control touch-screen. Can all the plugs in the 1080 handle different monitors? Would it help to bridge two graphics cards with SLI or something similar, and if so, how to use them with the monitors?
And a minor point I ran into today is whether my current chassis's (Antec LanBoy Air) front panel with USB 1 and 2 plugs can be used with the new 3.0 and 3.1, or whether I need to invest also in a new chassis to get an updated panel - hopefully not? I'm assuming at least my power supply and water cooler I can keep, since it's also 1151 in my current i7 2600K setup.
Thanks again for your advice!!!
