The upgrade argument for desktops doesn't stand up anymore (www.howtogeek.com)

I haven’t thought about it in a while but the premise of the article rings true. Desktops are overall disposable. Gpu generations are only really significant with new cpu generations. CPUs are the same with real performance needed a new chipset and motherboard. At that point you are replacing the whole system.

Is there a platform that challenges that trend?

Edit Good points were made. There is a lot to disagree with in the article, especially when focused on gaming.

Storage For the love of your data : storage is a WEAR component. Especially with HDD. Up until recently storage was so cheap it was crazy not to get new drives every few years.

Power Supplies Just because the computer still boots doesn't mean the power supply is still good. A PSU will continue to shove power into your system long past the ability to provide clean power. Scope and test an older PSU before you put it on a new build.

This doesn’t make any sense, especially the 2x 3090 example. I’ve run my 3090 at PCIe 3.0 over a riser, and there’s only one niche app where it ever made any difference. I’ve seen plenty of benches show PCIe 4.0 is just fine for a 5090:

https://gamersnexus.net/gpus/nvidia-rtx-5090-pcie-50-vs-40-vs-30-x16-scaling-benchmarks

1x 5090 uses the same net bandwidth, and half the PCIe lanes, as 2x 3090.

Storage is, to my knowledge, always on a separate bus than graphics, so that also doesn’t make any sense.

My literally ancient TX750 still worked fine with my 3090, though it was moved. I’m just going to throttle any GPU that uses more than 420W anyway, as that’s ridiculous and past the point of diminishing returns.

And if you are buying a 5090… a newer CPU platform is like a drop in the bucket.

I hate to be critical, and there are potential issues, like severe CPU bottlenecking or even instruction support. But… I don’t really follow where you’re going with the other stuff.

    That is the point of the article.

    The problem my friends has is that he is rendering video so he has a high performance Sas host adapter on the same PCI bus as the GPU. He upgraded both hoping the 5090 would play nicer with the sas adapter but he can't pull full disk bandwith and render images at the same time. Maybe it's ok for gaming, not for compute and writing to disk.

    The thing with power supplies, they continue to provide enough power long after they lose the ability to provide clean power under load. Only when they are really on their last legs will they actually stop providing the rated power. I have seem a persistent networking issue resolved by swapping a power supply. Most of the time you don't test a power supply under load to understand if each rail is staying where it needs to be.
