A better place to check would be Elitistjerks.com searching for a good spreadsheet or a good config of rawr, rather then just asking here.
Haste will *always* be the best stat at *some* point, the question is whether that point is obtainable in the current level of gear. Maxdps.com doesn't take into account 2pc and claims at around 9k AP, 25% crit 3.6 speed weapon, 251 DPS weapon in a perfect rotation 20haste rating>20 str.
Take this with a grain of salt, and find something better calibrated to your gear before dropping thousands of gold on the switch.
