What type of PC to buy

Graduation, My birthday, and christmas are coming up soon and my parents are aware of me wanting to get a decent pc for college. I am looking for something that is fast with gaming, runs bots with ease, and is affordable and will last me through the years. Not looking for something super expensive, Probably looking for something under 800 how ever anything close to that i will gladly look at. and help for computers i could look into, what to buy, or something that would make up a good pc would be greatly appriciated! thanks!

edit: would like to spend less then that 800, preferable close to 600 but any suggestions help

 

Laptop or Desktop? Would you assemble it yourself if a desktop?

 

desktop, building it is a possibility, all depends on the complexity and if my brother would be able to help me
