I want a desktop equipped with a GeForce GTX 460/560 for developing some scientific computing applications using CUDA.
Right now, I wish to buy only one card. But in the near future I might need to purchase another card to do multi-GPU CUDA
Hence I have 3 questions:
1)Does this mean I have to go in for a SLI equipped motherboard?
2)Is the SLI technology used in multi-GPU CUDA programming? D
3)If not, then do I just have to purchase another GTX 460/560, fix it into appropriate PCIe slots and install the GPUDIRECT 2.0 drivers to start using multi-GPU CUDA?
Being a CUDA /GPU noob I would really appreciate some simplfied/detailed explanations.
