ds3r or ds3p

[jarrod10]

hey im building new rig with 8 gigs of ram and a q6600 and i was wondering if i should get a ds3r or a ds3p?

I'm in a similier situation needing to upgrade my current system so that I can have a second relatively fast machine. I too am looking at both of these boards and the only reason I can see going with the DS3P over the 3R would be if I needed the 4X pcie slot. Maybe this has been posted somewhere already but will Nvidia's PhysX (Cuda) technology require an SLI enabled board or just a second full sized pcie slot in general?

To answer the OP's question, other than what I stated above I believe these boards are almost identical spec wise with the DS3P being a bit more expensive due to the pcie slot configuration.

Do you need the extra x16 slot or not?

I read that Nvidia's strategy is to take the PhysX engine and port it onto CUDA, which stands for Compute Unified Device Architecture. All of Nvidia's existing GeForce 8 graphics processors already support CUDA so the cards will be able to run PhysX. Thus I don't see the need for a SLI enabled board unless you plan to implement SLI technology. But to answer your question, it seems like to run Nvidia's PhysX (Cuda) technology all you need is a single GeForce 8 graphics processor. Which means you could use the 3R or the 3L, as second 4X pcie slot is not required. The reason is, it's just gonna be a software download. Every single GPU that is CUDA-enabled ( i.e., GeForce 8 cards) will be able to run the physics engine when it comes.
