I have an old PC.

Currently having 512MB RAM and the Xeon E3-1240 CPU with 500W PSU.

Is this worth keeping to throwing the GPU in, like 3090 or something, or is this too old to being useful? It has the PCIe 2.0 but my friend says the throughput is less important to LLM use.

Just was curious in discussion with my friend.

Thanks. 😎👍

    512MB RAM

    When did they thaw you out of ice?!

    Jokes aside, you probably mean 512 GB of RAM. That platform is slow and old, and that is at best DDR3 1333 dual channel, much worse than even bottom barrel DDR4 dual channel.

    A 3090 will not care about it as long as you are doing pure GPU inferencing and not touching the GPU, if not DDR3 and PCI-E2 will kill the performance.
