Yes there are physical differences. I looked at the Rev 1.0 picture on Newegg and compared it to my rev 3.3. At a glance, I found:Is there an actual physical difference between the different revision boards for the DS3? Or is it due to a newer BIOS version?
My that board looks lonely waiting on the Intel price drops to get the CPU and AMD/ATI to cough up the R600/HD2900 series vid cards.
3.3 has solid state capacitors ... supposedly, more durable/higher quality. And support for intel's 1333 mhz FSB chips when they are released (e6x50, I think).
The solid (not solid state, solid state = semiconductor) capacitors are the distinguishing difference between the GA-965P-S3 and the -DS3 model (D for 'Durability' according to GB). The 3.3's claim the 1333 FSB support officially, although all revs could achieve that. I also think they added quad-core support in either rev 2 or rev 3.3.3.3 has solid state capacitors ... supposedly, more durable/higher quality. And support for intel's 1333 mhz FSB chips when they are released (e6x50, I think).

Yeah I went ahead and ordered the motherboard two weeks ago when they put it on sale for 113.99 for two days. I was worried that on price drop day I might find a CPU but have key supporting parts sold out (like the 'DQ6 is currently). I'm actually considering using this ancient PCI (not PCIe) graphics card I have to get the system up and running while waiting for ATI.
OrangeGator,
Somehow, and I'm not sure how, I wound up finding the specs on GigaByte's web site. My efforts to find it again have proved futile! I also called them and they confirmed the 6 phase power regulation. The VRMs are not as heavy duty so if you are planning heavy duty games the 3.3 might better suit your needs. Neweggs specs are all screwed up so don't go by them!
