Last upgrade: overclocking Radeon9800Pro:
I succeed to overclock GPU from initial 338 MHz memory a 378 MHz GPU core:
to 351 MHz memory, 392 MHz GPU core.
I also equip the card with new cooler - Thermalright V-1 Ultra, slightly modified to don't block nearby PCI slot.
even if overclockig is only by 2-3%, SDLbench faster by another 8%.

Slow points (frames/sec):..12.6582 235.294 1.6632 59.2593
Fast points (frames/sec):...324.461 118.081 81.6587 29.6777
Rect fill (rects/sec):............23141.2 512000 7474.45 240941
32x32 blits (blits/sec):........63015.4 372364 61134.3 372364
Nice! Just now, my Pegasos have overall score 3341.66 in http://hdrlab.org.nz/benchmark/gfxbench ... esult/2155
It is faster than some SAM460Ex with HD cards, even if this card have no compositing under AmigaOS.
