How much should I spend on a custom gaming PC?

An awesome custom gaming PC will cost around $2000 in parts. When spending that amount you will get good gaming performance and if its your very first gaming PC you’ll have room to upgrade it in the future. We recommend avoiding a prebuilt gaming PC for competitive gaming. Also focus on getting an aftermarket cooler instead of a stock cooler, so you can overclock.

Should I build my own or get a pre built PC?

Building your own is better for future upgrades and proofing your PC. The best prebuilt gaming PCs are not bad builds, its just you can’t swap out parts as easily when someone else has built it. Things such as adding more storage or switching to an AMD CPU get more tricky when you dont know all the parts. Opinions are divided in PC gaming and you won’t get a straight answer for the most powerful gaming PC, so you have to do your own research and combine your own PC build.
