The first computer I could call my own was a Pentium 75 with 8MB RAM, it was slowly upgraded a part or three at a time through the years until, huh, I just realized I have never done a completely fresh build for myself. At least one part from the previous build has always remained, only to be replaced at a different time in the future, a disk, the case, the power supply, a random drive bay insert. Hah, only took my like 27 years of working on my PC to make that realization. Anyway, I guess the biggest revisions were probably when it went from that pentium 75 to a Cyrix 133, and then K6 - 2 with an ATI Rage 128 and then TNT 2 before being upgraded to an Athlon 700, then Socket A Thunderbird 1400 and Geforce 2 MX 400, XP 2100+, 2400+ then 2800+ with a Radeon 9600 Pro. I finally had a steady job at that point so I bought an, Abit socket 939 board and paired it with an Athlon 64 3800+ and Radeon X800 XT, then an Athlon 64 X2 4800+ and X1800XT. Honestly from then on its been a ton of changes, literally dozens of CPU's and GPU's from AMD, Intel, and Nvidia. The current config is a B650 board with a Ryzen 9 7900X3D, and RX 7900XTX which I just recently swapped to (got a sweet deal on the 7900X3D and 7900XTX), replacing a Threadripper 1920X and RTX 3080. I also have a couple of dedicated retro computers, one for Dos, 95, and 98 with a K6-III+ 450 running at 550 Mhz, my previously mentioned Geforce 2 MX400 I still have (first GPU i Bought with my own money), and a Soundblaster Live with a 64GB SSD. The other is an original Athlon 64 3200+ with a Radeon X800 XT for late 98 and early XP. Technically I guess there is a third one for windows 7 but its currently incomplete, I7 2600, 16GB RAM, RX 470 4GB. I'm looking to change that to an I7 3770K, and RX 5700 XT or RTX 2070, but honestly it wouldnt surprise me if that isnt complete for a few years since I am sure that I will keep sniping parts from it for builds for others since those parts are all still useful. Eh who knows, maybe itll end up being AM4, TR4, or X299 based instead with an RX 6900 XT or RTX 3090 in a few years, Windows 7 definitely allowed for a ton of different options.
