i really wish I could have eeked out one more GPU upgrade before the shit hit the fan..but GPUs are at the point now where you gotta upgrade the PSU to upgrade the GPU since power draw demands are getting absolutely donk.
Weird aside, but I have a 14900k which just eats power. About 400ish watts draw during CPU benchmarks for total ststem draw. I had a 1000w psu and finally got a 5090. Now a 400w cpu + 600w gpu should not work- but it did. I did stress test both at the same time and hit 1100w, but it lived. Thing is, most games do not stress borh CPU and GPU at max at the same time, so real world usage I was always under.
Still, I want headroom, so I got a deal on a 1500w psu. New PSU is more efficient, and running the same simultaneous cpu/gpu benchmark I hit about 960w, so the efficiency bump kept me under my old psu limit. It did lead me to get a new PSU, but technically it would have been mostly okay.
GPUs at least are actually not that expensive right now. Aside from the 5090, they're mostly close to MSRP, which is a pretty novel situation. I was waiting to upgrade my whole system for that, though, because my CPU would be a bottleneck at this point, and that's not really an option now because of the crazy RAM prices. The past few years have been super frustrating for PC builders.
for now
by the time i can afford it, and a new PSU, the ram issue will probably see GPUs skyrocket as well. Especially with companies cutting consumer production for AI production.
Yeah. At least I managed to pick up a used 3070 a couple years ago. I'll just jolly along my old i7-7700k system for a few more years...
