Buy a New One or Rebuild

I've used this machine for twelve years. The computer works well. It's stable and maybe not the fastest on the block. It does NOT work with Win11. The question is should I obtain a new mobo and RAM? I upgraded over time so that I now have this: Win 10 Home Pro 64, CPU Intel i5 760 Lynnfield, 24 gb RAM DDR3, Gforce 710 Graphics. Sandisk SSD 1tB, lots of USB3 drives and peripherals per the usual stuff. IF a mobo and the proper RAM can be assembled and keep the GUI, i5 chip etc I could in theory have a new machine. MAYBE i could invest in a newer CPU. Maybe. Will the PCI on a new mobo accept gear from some years back?

Thanks everybody. This is the place!

I'd drive the current system till it died and went to PC Heaven. Or until you must use Win 11... I hate taking parts out of a pc that will have no use and will be thrown away.... But that's just me.

Finding out if the OLD CPU will work on a newer mobo would be the thing to look at....

To use Windows 11 (starting in 2025) and have it supported, you will need a new CPU and a new motherboard. I would continue with the current system until then as long as it is meeting your needs. By that time, even newer and faster hardware will be available, possibly at lower cost as well.

As always I receive sage advice. I'll keep the computer I have until it rusts into total obsolescence. You know..."if it ain't broke" etc. Thanks!
