Funny thing: when I tried installing it, I already had the latest driver version
anyway, I tried the lastest 2.5 SDK, and indeed, it solved the 100% CPU issue
too bad it's still 1% slower than 2.1 SDK on my overclocked 5750, same driver version
haha 5750 is garbage move on
I had to RMA my 5850 because of artifacts, so waiting for them to mail me a new one
but I HIGHLY suspect that all 5xxx cards are faster on 2.1 SDK
I will test and report back when I get my 5850
