Navid,
I checked Sapphire's website out at the URL below.
http://www.sapphiretech.com/
In the support forums, there were a lot of frustrated owners of the 9600XT
128mb and 256mb versions of this board that could not seem to get the
"overdrive tab" in the ATI CAT driver version 4.1 to work. I saw nothing
about the 9800XT version of the board mentioned - as a matter of fact, I did
not see the 9800XT version of the board mentioned anywhere in the forum,
almost like it wasn't released yet or something.
Regarding the 9600XT issue of not recognizing the thermal sensor for
overclocking, I saw several posts that Sapphire responded that they were
looking into the issue with ATI regarding the missing overdrive tab in the
4.1 release of the CAT's. Hopefully, it will be a problem quickly fixed by
either Sapphire or ATI.
You can go and see for yourself and read the posts - that will give you the
best indication of what is currently going on.
Regards,
Tom
