well as we don't knowwhat program or your current system i reccomend buying the most expensive computer you cna find and that should fix it... might set you back 10-15 thousand to start
or you can tell us what pc you have if its a prebuilt like a dell or gateway the model, if home built the mobo/cpu and gpu with hdd ram psu and other info as well as what software you are trying to rn and we can probably bring that 10-15 thousand pric tag down to a more reasonable lvl
