My friend an I both purchased a rig around 5 years ago. He got Q6600 and I got the phenom 710.
Since then I upgraded the processor to a phenom II x2 555 which I unlocked to x4 and overclocked to 3.8ghz. This computer sits at my mom's house.
I got myself another cheap computer when I was a student, athlon II x2 (overclocked), 780g board. My brother took it for his apartment and when memory prices went down I upgraded the better computer's ram to 2x4gb and moved the 2x2gb I had to the other computer.
Right now I'm typing on a computer I got myself with 7870 XT graphics, 990X board, 2x4gb memory, 128gb SSD, and my trusty old phenom II x3 710 overclocked to 3.2 ghz alongside an old arctic xtreme hsf I got when I bought this cpu. This cpu will probably be a placeholder until I feel like upgrading, and then I'll put it in my brother's computer. However, beside some minor stuttering and lagging on huge multiplayers this cpu works just fine so I don't think I can justify the upgrade just yet.
All in all, throughout all these upgrades and swaps, the only component that's unused is an old 2x1gb ocz memory kit. Most other components are hard at work as they are overclocked.
Getting back to my friend, he's stuck on old and pricey ddr2, pcie 1.0 and a dead platform.
AMD is great for people like me and you, too bad there are so few of them.
