I'm currently in the process of upgrading my pc.. It's an interesting exercise in making sure things are safe and the upgrade is as painless as possible. My pcs are only used for LR, PS and printing. Internet work is a minor consideration only and has no bearing on the final choice.
My original system is coming up now on 6yrs old. It has had an increase in ram to 24gb two yrs ago and the video card upgraded to a Nvidia Quadro K2000 to support the 10 bit Eizo I use now.
It's a Win7 64 bit system, It has a 500gb ssd as the OS and Lr / PS drive, a 120gb Ssd as a swap drive and 4x1tb WD reds in raid 1+0 to serve as the archive. I have various external drives as well for backup.
The new one is right on the cusp of Win 8.1 to Win 10.... ffs. Ah well.
The physical system is as follows
i7 5930k chip
Asus x99 deluxe mb.
Samsung 850 Evo 1tb SSD for OS and programs
Samsung 850 Evo 500Gb SSD for LR catalog
Samsung 850 Evo 120Gb SSD for windows and PS Swap files
Quadro k2200 4gb video card
4x5Tb WD Reds in an onboard raid 1+0 for a 10Tb drive for archive
plus a few other accessories.
The interesting part I am finding is to make this upgrade process as painless as possible. Finding all of the original software for the various programs and devices I use is interesting to say the least.
I have backups happening now after cleaning the machine up. The info in the archive in particular will need to be transferred successfully otherwise I'll be in trouble. So, I'm looking at 4 external HDs with backups on. I have boot disks with the data restore program on... Making sure the LR preferences, the print drivers settings for papers, the various camera, printer and screen profiles I have built are safe is of paramount importance. If I lose them, a long period of rebuilding will be facing me.
What's the odds that I'll have forgotten something in the middle of it.....? I figure I'll be out of action for around a week or so during this time..
