An x445 with two 3.0GHz DP processors and 2GB of RAM is running a processor-intensive floating-point geological application that calculates pressures in the earth’s crust.  It takes a long time for each calculation， and the director of computing wants the calculations to take less time.  Memory addressed by the application may also be a bottle neck.  Which of the following will most improve the ability to run the calculations in less time？（）

• A、Replace the two 3.0 GHz DP processors with four 3.0GHz MP processors with a 4MB L3 cache and 4GB of RAM
• B、Replace the x445 with an x366 with four 3.66 EM64T processors with a 1MB L2 cache and 4GB of RAM
• C、Replace the two 3.0GHz DP processors with two 3.0GHz MP processors with a 4MB L3 cache and 2GB RAM
• D、Replace the two 3.0GHz DP processors with four 3.0 GHz DP processors with a 512KB L2 cache and 4GB RAM
