What to look when buy a computer for HASHCAT

What i should look up, i am going to start in a job for 1 year to know, in some month ill have a available budget off 4500/5000$ for sure i dont want to spend everything but i can. I will use the computer for mostly everything, editing/gaming and more things. But i want to put like main goal to achieve a nice score in hashcat pw/s for decrypting at nice performance, so i have not to pay montly a Dedicated server like now.



Thanks
