  • What “merits” needing a CPU upgrade? I upgraded from a core i9 11950h to a 13900h machine because I needed more performance. That 11th gen machine still looks pristine besides one spot where a cat bit the corner of the lid. Even my piddling around machine wasn’t up to snuff and upgraded from a 10th gen i5 to a 12th gen system. That machine’s keyboard was a bit worn when I first got it, but it’s not (appreciably) worse now. Besides that and maybe the palm rest the chassis is in pretty good condition. Why does it matter if the keycaps are a little smooth? Or there’s a small scuff on one corner. Or a cat punctured the bezel of the display and somehow didn’t break anything.














  • High end GPUs are always pushed just past their peak efficiency. If you slightly underclock and undervolt them you can see some incredible performance per watt.

    I have a 4090 that’s underclocked as low as it will go (0.875v on the core, more or less stock speeds) and it only draws about 250 watts while still providing like 80%+ the performance of the card stock. I had an undervolt that went to about 0.9 or 0.925v on the core with a slight overclock and I got stock speeds at about 300 watts. Heavy RT will make the consumption spike to closer to the 450 watt TDP, but that just puts me back at the same performance as not underclocked because the card was already downclocking to those speeds. About 70 of that 250 watts is my vram so it could scale a bit better if I found the right sweet spot.

    My GTX 1080 before that was under volted, but left at maybe 5% less than stock clocks and it went from 180w to 120 or less.
