Gaming Laptop:
For "work" at LAN parties: EVGA SC17 stock
Work computer at home (sometimes game, though drivers are not optimized):
HPE Proliant DL980 G7: Dual Xeon E7-4870, 1 TB RAM SAN, 3-PAR StorServ 10 TB Flash Array, dual Quadro RTX 4000 (an off-the-shelf 2080 Ti can beat it now, I think). Used mostly for statistical work. Very rarely game on it due to time or other work that I have scheduled in the background to run.
"Gaming" desktop:
26 year old IBM Aptiva Model 2144-971 486DX2 66 MHz, 8 MB Ram, 540 MB classic HDD (which is the part that I have to replace most often), DOS 6.2/Windows 3.11, configured for Star Control (where my user name comes from although I am known by a different handle in the community), Galactic Civilizations, and Ultima VII. I have five 486 models in storage including a pristine new in box one and they are specifically insured.
