I bought mine-craft almost a year ago specifically to play crazy craft 3.0
but didn't realize that it was a massive mod pack and you need a decent PC for the game,
I can play mine-craft okay with optifine(about 30-50fps)
But i can't even load crazy craft , it comes to the mojang loading box and says not responding and then eventually closes, and i'm pretty sure even if i could get it up it would be lagging to much to play,
My laptop is 4 years old and doesn't have the best specs,

My ex had a good gaming computer(i think) and his PC could ONLY run crazy craft 2.0
So ive been trying to figure out what PC I need that will DEFINITELY let me play cray craft 3.0 with little to no lag
(as i'm worried i will spend all this money on a PC and it wont work especially since ill be buying it for the main purpose of crazy craft ill be heartbroken if it wont run)

I don't work and don't have much money at all so I would prefer cheaper the better but as long as it will definitely work and isn't ridiculously over priced then i'm happy

If possible to list all the parts i need for a CHEAP-ish PC(with little to no lag) that will run crazy craft, and possibly a list of all the parts I could spend more money on for a better part to reduce lag, or better performance etc

thanks in advance :)
