People, get the Sapphire. PowerColor has those horrid Infineon 3.3ns memory.
What's the problem with Infineon 3.3? I'm just curious because that's I have on the 9500 non-Pro I just got/installed. Clocks up to 303Mhz on the memory, appears to be stable, and it's faster than the memory that I read was supposed to be on the card (3.6ns). Is there something wrong with Infineon chips? Is my beautiful new 9500 going to explode in a burst of face-shredding shrapnel? Will fire come shooting out of my front USB ports?
They have low voltages, and it's nearly impossible to get them to run anything over 303MHz.
Volt mod.
But from my own testing this afternoon (Q3A test, bilinear, no AA, no AF, 1152x864, 32bpp color and textures, all other quality options maxed), the gains from memory speed increases are negligable. Half a frame/second was what I could measurably reproduce during the tests (that is, for each 5Mhz the RAM was OCed, approximately 2.5 fps were gained). I'd expect that increasing the resolution or turning on AA/AF would lower that even more.
At any rate, from what I've read on Rage3D, the 9700 series didn't suffer from the low voltage issue, just the 9500 non-Pros. It also appears that the +5v voltage has a more significant impact on overclocking 9500 and 9700 cards than the mem voltage.
