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. 😎👍
