What are your current PC specifications? As for me, I just run a modest Core i3 10100 with just 4GB of RAM and a 1TB HDD with no GPU. It’d be very bad value unless you get it for very cheap, which I did. All parts for the PC cost around 200 USD, which I think was a great deal.
i7-12700k, RTX 3090, 32 GB DDR4, 2TB SSD + ~80TB HDD
Picked the 3090 since I wanted to be able to run AI models locally while also playing a lot of games. It’s been pretty useful for running language and vision models for my assignments.
