Using multiple GPU cards for serial task

Hi,
I am planning to buy a GPU for faster computation.
Since I am not too familiar with GPU computing, I would like to know if multiple GPU cards would provide me additional speedup in my numerical computation.
1) It seems to me that parallel task would certainly benefit from having multiple GPUs on my workstation. 2) Can serial task also benefit from having multiple GPUs?
I would be looking to speed up the following operations: 1) Matrix-vector multiplication 2) cholesky decomposition/factorization
regards, DK

Current versions of MATLAB can only use one GPU card per parallel session, so serial tasks would not be able to benefit.
