Baboonguy, the 8RDA+ is a great buy, and it <U>will</U> do the job for ya!
I got mine from MWave about 2 months ago, and it came with the A1/C1 NB. It's running at 210FSB without any mods, and could probably go higher. Although the Rev 2.0 has been announced, it's not available anywhere in the USA yet.
The 8RDA3+ is a different board, which, as Shimmi said, has some features which aren't found on the 8RDA+. It has SATA, it has voltage adjustment for the MB (NOT found on the 8RDA+...this is why people did all the 'voltage mods' on the older boards..), and the onboard sound is not considered as good as the 8RDA+.
At the rate the 8RDA+ has been selling, if you bought one from NewEgg you chances of getting the A1 chipset are virtually 100% unless you bought a refurb. They are selling all the boards they can get their hands on, which means no "old" stock (with older chipsets). They are also great about RMA's if you run into a problem.
