To answer your original question: you can mainly tell by doing benchmarks and watching your CPU/GPU usage. If your CPU is maxed the whole time but your GPU is chilling at 50-60% usage while you're getting below 60 FPS, you likely have a CPU bottleneck. There are a number of free benchmarks out there, and several "AAA" games will typically have one too (Forza, Returnal, and many others) so you can tune your system.
So buying a 4080Ti without the supporting parts it needs will limit how much performance you can get out of it. Nowadays RAM typically is not the bottleneck.
I had a Ryzen 7 1700 with a 2070 non-super until earlier this year with next to no problems. The only reason I went to a 7800x3d was because it was bottlenecking the software I used to make music.
The new Prince of Persia roguelike is pretty good, although I've hit a wall recently and am too stubborn to look up a walkthrough. Lots of fun otherwise, though.
I'm in the same boat, in the early days of Android (Galaxy S 1 days) I used to go to their site just as frequently as Tom's Hardware, TechPowerUp, etc. because they were on top of most new customizable ROMs if I remember right.
I haven't had a reason to go back since it has become increasingly more difficult to get a custom ROM on any Galaxy phone, and I almost completely forgot about the site until this announcement.
I'm a music producer and there is/was a "Loudness War" and several people say loud won. To clarify: for your tracks to qualify when uploading them to Spotify I believe they have to be a minimum of -10 LUFS. I'm not going to pretend that I know what a LUFS is fully, but I have software to tell me where my LUFS is at. If you don't hit at least -10 LUFS they will fake it for you, with usually terrible results.
So now all producers are mixing to -10 LUFS and higher (-8 or -9), all for the sake of possibly getting radio play in the future, although not all music sounds good when mixed so damn loudly. I know this is tangentially related but
If I get 45k a year, along with a Jacuzzi with free maintenance for a year, I'd probably take that because it's a better deal than a lot of teachers get.
Typically, though, most racists who go to college or the military after leaving their racist family/town learn that Black people aren't "savages" like they're taught; they're just people like anyone else.
This girl's college experience seems to have done the opposite, emboldening her to go super racist while intoxicated. It's sad, really, that at 21 she had such evil thoughts about another race.
