Actually I think the core speed makes little difference in GF3 cards. It is the memory speed which produces the most gain in speed. There seems to be a point where increasing the memory speed even makes less difference form a report I saw somewhere recently. It was around 540 to 560 where it basically topped out increasing speed generally.
Perhaps that is why I saw much better results overclocking core over memory.
Memory tops out very quickly, while core keeps going.
While not exact, the following is a good idea of how overclocking relates.
For every 1 MHz you increase core speed, 3dm2k1se scores go up 35, (or for every 10 they go up 350).
For every 1 MHz you increase mem speed, 3dm2k1se scores go up 1.5, (or for every 50 they go up 75 points).
Running VT GF3 Ti500 with XP1600+ running 160x10.5
At 255/545 scores 3dm2k1se of 8940.
At 255/560 scores 8968, or 28 points with the 15 MHz mem increase.
At 255/580 scores 8997, or 29 more points with 20 MHz mem increase.
At 257/580 scores 9072, or 75 more points with 2 MHz core increase.
At 259/580 scores 9143, or 71 more points with another 2 Mhz core increase.
