If you really need more fmax then /e is the way to go. The current issue of Alteras newsletter has a complete table of chips and NII cores and fmax's.

They show the /e going 201MHz on Stratix II. For Stratix I they show 141MHz for /f, 130 for /s, and 144 for /e.

For Cyclone I got NiosI going 140 all internal, 120 with SDRAM as data only, and 110 running out of SDRAM.

Don't plan on these speeds in your real world app though. Once I added all the required peripherals to the Avalon bus (and complex firmware) I'm down to 75.
