Rower has identical specs to my computer, and was running V60 awhile ago when he did the tests.
he got 280-290 (v60) to my 309 (v62) on the 1st test when we finally both had the same plugin, and i think Rower said he was getting about 125 on the second one, but that was probably with v62.
So I just tried the flash benchmarker on my dual 1.25 with the old Safari (60) and the new one and there really wasn't any difference. 83-86 for both on several runs.
