I decided I needed a major puter upgrade for AH3. This is the only game I play, and is likely the most resource-demanding task for this puter. I'm mostly retired and did not want to spend more than I need to, and also applied the principle that it's likely best to build only what I need now, since if I want something more in the future upgrading will get me more for the $ when I need to upgrade. So here's what I built:
O/S Win 10 moved over with SSD from my old system
GPU: Gigabyte GeForce GTX 1060 Windforce OC 3GB DDR5 $209.99
CPU: Intel I#-6100 3.7 Ghz $118.2
Cryorig M9i CPU fan $26.97
RAM: Ballistix Sport 8GB DDR4 $37.99
Mobo: MSI B150 Gaming M3 $103.95
WD 1 TB HDD $49.99
PSU: 400 W Corsair CMPSU-400X (free, used from my old system)
Case: Antec P-100 $74.99
Total cost: $622.08
If I really wanted to go extreme low-budget I could have shaved another $120 off, and had the same functionality for about $500.
Lessons learned:
I really enjoyed building it! Took my time, worked slowly and deliberately and feel like I learned a lot; very satisfying.
Despite info on the internet to the contrary, I found it trivially simple to move my SSD with Win10 installed from the old system to run the new system. It took about a half minute for Win 10 to note new Mobo, CPU and Ram, and then run the new system with nary an issue.
I could have saved money on the case and motherboard, but wanted some extra features. The case is very easy to open and work in for upgrades, and both the case and motherboard support lots of USB ports; if I decide I need a much more powerful machine it would easily accommodate more cooling, etc. I could have also avoided the nicer CPU fan and saved $ by going with the stock Intel fan.
This build is so quiet it's almost spooky. I 'm currently using a 1080p monitor. The machine runs AH3 with all the settings full on mostly at about 60 fps, and sometimes I've seen it dip into the 40's. I'm very happy with it. I've never seen AH3 use more than about 40% or so of my video DRAM.
Thanks to Latrobe and my sons for help; I found this site was very useful too: Logicalincrements.com
I hope this helps some of you who are trying to decide to build or upgrade!
