Does anyone know if this is possible?

I was wondering if it would be possible to upgrade the CPU in my old eMachines T3990 PC, since my current one can't easily handle what I would like to do on my PC. (My processor is a 3.20 GHz Intel Celeron D). Celeron D seems to use the 478 Socket and the only other processor made for that socket was the Pentium 4 (which is discontinued). Any ideas?

In all honesty get a new processor and motherboard. You're running dated hardware. For a couple hundred bucks you could get a cheap MOBO and CPU. This may mean new components elsewhere as well. But if you do some looking, I'm sure you can find a MOBO that has the connections needed for the rest of your hardware.

yeah celeron D is very old, even P4 is pretty old. Just as noodles said buy a cheap mobo, processor, ram, maybe video card and your good to go

I think it depends if your operating system can support it too but I'm not sure.
