yes. i know. it's very early to be considering this but i need to think about this because i'm concerned that my current PC is dying
the damn thing is like 5 years old, and it's starting to have a lot of sudden lag spikes. the CPU isn't the best either, and its age shows whenever i try running certain programs.
for reference, here's my current specs on this old thing:

anyways, enough about my old computer for now. people can reply about that if they really feel like it
i need a computer that's not exactly amazingly powerful, but not weak/not made for games, either.
the games i usually play are like
- team fortress 2
- terraria
- minecraft (sometimes, not too much anymore)
- enter the gungeon
- (rarely) garry's mod
- blockland
- 20XX
and probably some other games i'll buy over christmas sale or my birthday if i have any leftover money i guess
basically i play games that can be intensive at times, but most of the time not really. nothing like crysis or some stuff like that
in terms of applications, i sometimes do video editing with like sony vegas. i've also been thinking about getting back into after effects music visualizers but that's something i gotta consider first.
nothing too intensive there, though. i'll sometimes tinker with audacity or fl studio, maybe forget with modules using openMPT. having more RAM for the memory sponge known as chrome might be nice too
budget-wise, i'm not too sure. maybe around $500-$600, but i can ask my mom about that later.
i've been considering maybe prebuilts from places like iBUYPOWER or CyberPowerPC, but i've heard bad things about prebuilts, at least from places like that or something. idk.
so forums, do you think you could help me with my issue? maybe help me come up with something that might work out well? i'll try to make a build on PCPartPicker and post it here, maybe get some thoughts on it.
