If the main purpose for your rig is gaming a laptop just isn't worth it.
Prebuilts get a bad rep. Don't get me wrong it's always more cost effective to build your own but the way things are right now you might get a BETTER deal going the prebuilt way then paying scalpers for a gpu/cpu at this point.
I would say figure out your budget then go from there. But if gaming is your main purpose get a desktop bro.
If you don't mind the wait i would suggest going to https://www.reddit.com/r/hardwareswap/ and just keep a lookout daily there for some good local deals. Built 5 rigs last year for friends all from parts from this reddit. Saved about 2-250 per rig. But again times are VASTLY different right now and everyone is scalping now due to product shortages.
The good thing about pc gaming is the parts normally hold their own in value. You can get a prebuilt now and just upgrade/sell old parts at your own leisure. Like alot of other people in here i sold my gpu/cpu/motherboard and monitor for damn near the same or even MORE then i what i bought it for 3-4 years ago. (Again this is due to the product shortages we are experiencing right now)
It would be multipurpose if anything. Game + school (programming, etc).
And yeah, that was the only reason I was gonna go prebuilt b/c I've been reading way too much about the scarcity of parts and ish. Ion really want know parts of that right now.
Like I said, it would be multipurpose but gaming would def probably be the primary for sure. Just dippin' my toes back in a world I had left a while ago.
I'ma have to check that sub-reddit out though and see what they talkin' bout.
