My ole 2008 built, intel core-2-quad-q9550 was still running fairly well using Linux until a stroke of lightning took it out last summer, but I was having major issues serving 4k video to my HT.As a custodian to a range of computers of all ages, I can tell you that a Core 2 Duo is no longer very much fun to use in this day and age even with an SSD and on Windows 7
With all this talk of 13 gen failures I'm glad I pinched a few pennies last year when I built my new box and went with a 12th gen i7-12700K (12core 8P-4E). I put about the biggest passive cpu cooler on it I could (DeepCool AK500 High-Performance CPU Cooler). With 64g of DDR5 5600 memory this guy is a snappy as I could ask for my needs. I don't game but do a lot of messing about with high res multich audio and video files.
I hope I get another decade or more from this guy, trying to wrap my head around purchase decisions about the latest tech was no fun this time around. Guess I'm gettin too old for this stuff. LOL
