lets say i have a big budget to spend on a cracking rig what card would u advice

[stepMode]

well you could check out https://sagitta.pw/ as already mentioned. I mean you don't have to buy one of their rigs, you could check the parts they use and decide own your own if thats what you are looking for.
You can of course change some of the parts to whatever you think is better.
Then come back and let the people here look through your decisions, imo a better way than just asking the community what to do.
