OCWorkbench.com have posted a review of the Chaintech AG321 GF3 Ti200 128MB. Heres a snip:
"In our tests, we overclock the card using nvmax. Although we are able to run steadily for q3 at 250/570, 3Dmark2001SE fails. To demonstrate maximum overclockability, we reduce it until 3Dmark2001SE works and all 3D graphics applications do not show any tearing. The performance gains over standard timings 175/400 is around 2.3% ~ 24%, the differences is larger when operating at higher resolutions."
