ive recently pulled the trigger and impulse bought a ryzen 9 3900x when the store i was at had one in stock. now im in the process of figuring out the rest of my build. the motherboard my friend has suggested is the msi b450 gaming pro carbon ac but currently, every store i look doesn't have it in stock, so im looking for suggestions on how to complete this build. currently stuck on what motherboard and ram to pick. also bang for the buck is what im looking for, not trying to break the bank more lol. I don't need wifi but it would be a plus (currently running none wifi build) i dont overclock i use the easy overclock my motherboard offers (p67 sabertooth) and my current gpu is rx480 sapphire nitro 8gb (will probably use until i save for another overkill gpu to add to my cpu) id appreciate the help.

so pretty much ive noticed my computer will have a lot of cpu load because multiple instances of programs will be open, for example anyone have any suggestions or even know how to solve my issue. its really driving me insane. i constantly hasve to make sure im running very minimal tasks or ill just be over loading and pretty much be lagging to insanity. https://gyazo.com/2b0bee331b27273d4ba989b343499d10

awesome thanks for the imput, i will be starting with python. and i wasn't planing on making anything useful like you stated. just wanted to see were this interest will take me. im still pretty young so a career change could happen after i complete my plumbing apprenticeship and have more freedom.

awesome thank you guys so much for responding to my thread, so far from people telling me in irl and on this forum i will probably be starting with python. again thanks for everyone that responded with input.

so i little a bout myself.. im an apprentice plumber who spends all my free time with my computer playing games, but im starting to get bored of playing games and would love to learn something new. me being from the trades i love learning things work and ive always had this interest. some guidance would be greatly appreciated.
