From my experience tweaking GPUs over the years, I can say that Heaven was definitely the gold standard for a while. But if you’re asking about the best GPU benchmarking software nowadays, I’d say 3DMark, especially the Time Spy test, is where it’s at. It offers much more detailed performance metrics and stress testing than Heaven did. Plus, it’s really useful if you want to fine-tune overclocks or compare scores across different GPUs. Definitely a solid step up for anyone serious about benchmarking today.
