Should I upgrade my RAM for faster compile times in Visual Studio?

Yes, if you’re currently on 8GB or less. Jumping to 16GB gives you breathing room because Visual Studio plus the compiler plus a browser will easily chew through 8GB, and hitting swap kills compile times. But if you’re already at 16GB, more RAM won’t help much—the bottleneck is usually disk speed or CPU, so an SSD (especially NVMe) will cut compile times more than going to 32GB.
