Hardware question

Hey, I’m shopping for a MacBook Pro used one for around $1,500.
Which one should I go for ? 13” or 15” doesn’t matter for me. I care more for which cpu, graphics and ram should I buy to get the best usage of SU and good rendering times.
Thanks

I think you should get as much ram as you can and buy used —NextTech was good to me. The last one I bought was mid 2014 2.8 Ghz (you might find one higher that you like) with Nvidia GT 750M
Macs are not going to be as fast as PC for rendering times. Depends on your renderer. I got the Nvidia so I could use the GPU for some rendering and for Optix denoiser (Thea). Still the MBP is low on the benchmarks.
