OC Workbench has put up a Chaintech A-GT61 GF4 Ti4600 review
The performance of this card is excellent just like any GF4 Ti4600 cards out there. As we have seen, the peak is reached and unless we super cool it and blowing cool air onto it. It will not help us to push the card to higher mem/ram clocks. The maximum we attained in our tests is 155/728 which is rock stable. The tool provided Turbogfx makes it easy to tune it up but it doesn't seem to allow 1Mhz stepping as it jumps to the nearest clock. e.g. I wanted to adjust to 365(730) it only allows me the option of 364 (728) or 368 (736). This is probably a software bug which can be resolved.Read more
