I recommended FC first becoz you have a 10x multi. Meaning the max you will get around if your lucky is about 10x280. That ram will do that speed with 2.5-x-3-7 timings without any problem at all .
The second one is if you want to be sure it will hit those speeds and still be in specs. I know for sure the FC will do around 285 mhz min . With aircooling , i doubt u will be able to go beyond 2.85 ghz.
Another good option is the crucial ballistix series. But i dunno if they are available in AUS yet. You can hit around 280 mhz with a little tweaking and voltage at 2.5-3-3-6 timings. And if you compare TCCD and Ballistix at same speeds and timings , ballistix has a better bandwidth. Its just how they are made.
And if you wanna be cool and run your memory hot like every other guy who owns a dfi skt 939 board , then the gskill GH or the OCZ PC4000 gold VX series are the perfect choice for ya.
heres a link to a review for Gskill FC by OPB ( for those who do not know who he is , consider him sort of my counterpart and my guru over at XS ) :
