What I wanted to see was if "old" programs which are not tested on actual hardware by SSDF is still able to compete with actual programs. Personally I say YES after this small match. And another point is that Genius3 does NOT seem to be weaker than Genius5. So all guys searching a cheap but strong program look for Genius3 e.g. and let it run on your fast PC. :-)
