Unless you're willing to spend $1000+ the real world performance differences aren't even that large: https://www.videocardbenchmark.net/high_end_gpus.html
- "I dreamt about you last night" - clearly a sleeping dream
- "I dream of being a doctor" - clearly a future desire
- "It's a dream come true" - ambiguous but the difference isn't important
In my experience there's also a cultural implication/expectation that the different meanings are often intertwined, i.e. desiring something so strongly you have dreams about it.
