Overclocking and Image Quality

With the Radeon 9700 Pro, I was able to get it up to about 365MHz on the core, and 360MHz on the memory– I could have probably gone a little higher, but didn’t bother to try. This is rather impressive considering that the 9700 Pro is built on the 0.15 micron core, and if I can get this speed on air-cooling with a stock heatsink and no voltmods, I wonder what ATI could do with a “9700 Ultra” of some sort. Clearly the memory is limited by its lack of cooling; I’d like to see this card with some Tweakmonster BGA Ramsinks on it…
One other note I wanted to add about the overclockability of this card is that it doesn’t seem to like high FSB speeds. I talked with another reviewer who was having the same issues with his 9700 Pro card– in a world of AGP/PCI locks and dividers on KT333/nForce/nForce2/Intel chipsets, it shouldn’t really matter, though my older KT266a board (I really need an upgrade…) didn’t seem to like it as much. I was able to take the FSB up to 160MHz before it would refuse to boot, whereas with most other video cards, this chip and board can do 166MHz FSB. Anyone want to buy me an nForce2? 😀
While this is not anything that I can show numbers for, I did notice that the 2D image quality on the 9700 Pro was brilliant; colors were also far more vibrant in 3-D. However, as I’ve said before, NVIDIA has also done a lot of work in that department, and the Ti4600 I was testing it against had pretty decent image quality (though not up to the level of the ATI by any means), and a lot better than my Ti200 in the IQ department.
