OCL isn't a basis for a thumbs down to tweaking because OCL benefits from the tweaks
True, but OCL runs robustly on all of my ATI cards and systems. Because I've tweaked my base clock, the enhancements that get applied to the CPU(s) also get applied to QPI (which is sort of like the buss in earlier systems). Thus, video card performance improves. So I get much improved OCL and OGL performance, plus I can better tweak my video cards individually in bios (and in other applicable utilities). See in my sig the Cinebench 11.5 GPU score my HIS 4890 achieves in OSX (47.90). In Windows 7, it's in excess of 84.
Not exactly the case. Apple never approved the 4890, nor any HIS card. Plus, OGL and OCL are, of course, open; its a technology that also exists on purely Windows systems. There are tweakers, like Netkas, who focus mainly on video card related issues and provide solutions applicable to many platforms. In other words, there's is cross-pollination - Mac->Hac->Mac->Hac->etc. Even Linux plays a role in the pollination chain and there are such chains that extend to other system components.
Open GL and CL are both important to me and my old 4890's serve me well on both fronts. I do have more recent ATI cards from the 5xxx and 6xxx families in other more recently built systems for which the same applies.
Finally, Mac Pros have never been admired for the video cards placed in them by Apple. Truth be told ---many Mac Pro owners are limited 2nd hand tweakers (relying on the success of pioneering 1st hand tweakers) because if you removed the sides from their machines, you'd probably find sitting in that lower or third PCIe slot a video card that Apple never sold retail or offered as one of it's overpriced options and if you pulled out the processor tray of, particularly, a 2009 Mac Pro you might find a Westmere or two, or how about those upgraded 2006 Mac Pros. In the end, we're just dealing with matters of degree, necessitated by a lack of meaningful options at the retail level.
