I mean, like most reviewers they test their games at ultra/very high to isolate the GPU performance. But realistically you shouldn't be expecting to run those settings at 1440p/4K for a budget card like this.
More 8GB cards sucks if that's what gets released, but it's not like you can't game at all without more VRAM. Just turn down your settings till a better deal comes along.
Not at all! I was able to graduate at 22, but I knew plenty of people that graduated much older for various reasons (changing majors multiple times, taking a year or two to work and/or help the family, etc).
If anything, it's more "embarrassing" to not graduate once you've started, but as long as you're able to (at least try to) get a job and contribute to society, who cares?
