Few, a few answers to give. Thanks for your support Alex and David. I'm on Windows 10 business. I have 4 main drives in my PC. I'm a computer engineer and built this one, yes a few years ago. An 2.5GB for my OS only.(SS) A 3TB for most working programs.(HD) A 2TB for photos.(HD) A 2TB for backup of all personal and program data.(HD) All the drivers are 10,000rpm with 16mb cache. I haven't upgraded the graphics driver as I think it has issues and don't like the new one's performance, but it is the second to latest, I think, but I will now check. The NVIDIA GeForce GT 640 ain't the latest but I think it should be ok for photos as it was designed for gamers. I tweeked the low voltage to help with cooling (AIR). Which is a problem due to the CPU, which is Intel(R) i7-6700K @ 4.00 Ghz. Logic 8. This should be way fast enough for LR. 16mb RAM I do run Mysql for an onboard Internet Server for off site backups, but this normally runs a night and not when I'm working. David this is just an email program, so only runs for seconds every 15 minutes. The Cat is stored on my 3TB drive of which 2.44 is free so no issue. As above Dave, I've lowered some operating voltages because of the temperature. Even with 2 chassi fans and 1 processor fan. Alex the graphics processor in LR was on auto. Now changed to off. Hope this info is of use.
