Why do you post arguments like these? Waterblocks obviously take a significant amount of heat out of the equation and are necessary for high-end overclocks, but a lot of your "matter-of-fact" rants are so grossly uninformed it's hard to know what you even mean.
To be certain, aftermarket heatsinks perform significantly better than reference. Of course not all aftermarket heatsinks are the same, but ASUS and MSI are great examples of GPU air cooling done right. Also, reference "heatsinks" are often not heatsinks at all - they are usually vapor chambers, which do not have heatpipes/"tubes," aren't that efficient at higher wattages (largely abandoned by the enthusiast PC market ~5 years ago), and are most often used in space sensitive applications.
All sources TPU.
Reference 780: Vapor chamber, ie no heat pipes

DirectCuII 780: Heatsink, 5 10mm heatpipes
1019/1502 Load: 71*
Reference 7970 Ghz: Vapor Chamber, ie no heat pipes
Matrix 7970: Heatsink, 5 copper pipes
Oh and ht4u's review of the r9 290
w/ performance BIOS while gaming:
Reference r9 290: 94* (obviously and with all of the crazy dips in framerates it's popular for)
r9 290 w/ mk-26: 58*!
Never mind the noise - TPU again, gaming load:
Reference 680: 36db
Ref 7970 Ghz: 51db
