What computer to buy

I decided to invest in a new computer after my old computer (that i spent over 1000!) was working very slow with all the heavy files.
Does anyone what I have to look out for? I’m willing to spend a nice amount.
Thank you

I think the most important thing is Ram- min 16gb but 32gb even better, and the processor speed should be high! If your getting an all in one than screen resolution is also very important.

If you have the option to buy a desktop that will always be stronger and will work quickest for videos
