When running a benchmark lets say like “Unique Heaven” does pc components matter? Memory/Motherboard/CPU 2.8~3.6 etc. Reason for this is because on YouTube you see a lot of people with ATI 6870/5870 GPU running different scores/FPS at same setting and speeds. If someone can clarify for me why that is, it would be awesome. Cheers!
With synthetic marks like Heaven, CPU can make a big difference, yes. This is why most people dislike synthetics... they are good like for like tests (trying different GPUs in the same system), but as real world tests, they're usually questionable. Memory can play a part, as can HDD performance too... also drivers have a great influence.
Yes. Motherboard doesn't make too much of a difference, but RAM and CPU can affect benchmark results just as much as a video card would. EDIT: Ninja'd
