Hi, Teslas should be superior when it comes to reliability, but otherwise, for Gromacs 4.6 GeForce cards are perfectly fine and no Tesla-specific features will provide performance benefits. The only exception is GPUDirect for InfiniBand which might not work with consumer boards -- , although I don't see why it wouldn't, except if it's simply disabled in the driver.
Here are the reasons (based on the list on the page you provided): - Faster Double Precision Performance - not needed; - Faster Data Transfers to/from CPU (with full duplex PCI-E) - will not help in 4.6; - Direct GPU to GPU communication - will not be used in 4.6; - Larger Memory Size - not needed (simulation with millions of atoms will run on a GeForce); - Optimized for InfiniBand - not sure about it, but it might not work; - Performance Drivers - simple solution: don't use Windows.
