Simply put, I have too many computers (7 at the current count). While all are functional to a greater or lesser degree, I don't need this many. One is presently loaned to my mother, so I can probably knock that number down to 6, but still! I've got (in order of age of me owning them) 1) OLD desktop (Athlon XP 3200+, GA-7NNXP, 2 GB DDR) - was going to use retro gaming rig - needs new GPU. 2) My old main rig (i7-980X equivalent Xeon, ASUS P6T7 WS Supercomp (powerhog board), 12 GB DDR3, 9600 GT, SSD, 500W PSU) - still works, but VERY heat-generating 3) Laptop (basic el cheapo AMD thing from about 2013, 6GB RAM, dual core, SSD) - functional, if not great. 4) Athlon 5350 rig (8 GB, micro ATX board, 400 W PSU) built to mess around with, not used much. [5) Kaveri rig (A10-7850K, 8 GB, SSD) - presently on long-term loan to my mother] 6) Present main rig (6850K, MSI Gaming Pro Carbon, Radeon Fury (old now), 32 GB DDR43000, 1500 W Enermax PSU, many hard drives) - generally OK, though GPU lacking for 4K gaming. 7) "backup" rig (5960X, AsRock X99 Extreme11, 5870, 750 W PSU, 16 GB RAM) And various cards lying around (old 465 GTX, a few 5570s, an old quadro, PCI expansion cards, etc). What's the best thing to do with all that? I figure there's a bit of cash tied up that could be used to invest in some newer kit. I figure I could amalgamate some things, sell off others. Really only need a main PC and a backup, maybe the retro one. Suggestions?
