Good Morning -
I saw the post before I went to bed, but I decided to just crash last night. There is a wonderful web site devoted to this "build a pc" effort -
Pick parts. Build your PC. Compare and share. - PCPartPicker that makes the effort really easy. Two years ago, I used it to build a similar PC - here is the story and all the build details....
A couple of things that might help.
- The OS that you run does matter. The memory utilization and allocation strategy of Windows and Linux are polar opposites. Windows wants to always maximize the amount of available RAM, while Linux takes the position of maximizing the utilization of RAM. What that means is that Windows will roll just about anything out to cache asap, while Linux will keep everything in RAM until it absolutely required additional memory, then roll out the least recently used set of pages. For instance, the other day I was actually looking at how my RAM was utilized while doing some post processing. I was running the OS (Win 8.1), FireFox, LightRoom 5.6, AffinityPhoto, Microsoft ICE and Oloneo PhotoEngine - all heavy hitters in terms of RAM utilization in parallel while processing a VERY large set of stitched and stacked panoramas. RAM utilization was pegged at 8GB - with 16GB installed. I would have thought that the memory utilization would have been higher. I really did not investigate farther. Over the last year I have been thinking about sticking another 16GB of RAM in - but it really appears that Windows is not interested in using it - so why bother. Things are running just fine as it currently is.
- With everything installed - lots of applications, I am only using 128GB of my 256GB SSD that is my system drive (c. I do roll off LightRoom's catalog off to my E: drive - which consists of 3 clustered physical drives - a 256GB SSD that faces the OS, and 2 - 3TB rotating drives. The motherboard I used turns out is able to support the Intel Smart Response Technology (SRT) - which makes the 256GB SSD appear to be single 3TB SSD (using the rotating disks in a RAID 1 mirrored configuration). Essentially, I loose no speed having both the LR catalog and all of my images on the E: drive. It was a bit tricky in setting this up. Actually, SRT only uses 64GB of the SSD as the front end cache - so in retrospect, I should have used a smaller SSD.
- The graphics card was a $50 low to middle end card, so that when LR decided to use the graphics cards for processing, I would have something to support it.
... and this little netbook that I am currently using on the kitchen table is dying a slow death (~5 years old). The keyboard is going along with the USB ports, that I continually need to unplug and re-plug the mouse into, so that it will be recognized. It's also just a single core, so it's slooooooow - but I wanted something to use while traveling that was small and lite weight.
- Well, yesterday while I was shopping over at Costco - I saw that they had a Dell XPS 13 Laptop, I7 quad core (they said??? - probably dual physical cores with 4 logical cores), 16GB RAM and 512GB SSD with their +QAD screen (3000 x 1800) for $1099. Super thin (metal case) and 2 pounds heavy.
