Are there performance recommendations with core counts?

We are installing SAS9.4M8 and have an additional consideration to think about and want to get your opinion. We are also running Platform Suite for SAS (Grid). For performance ... is it better to have more physical servers with lower CPU (8 nodes with 8 cores within a grid) or fewer physical servers with higher CPU counts (4 nodes of 16 core)?

Forgot to mention ... we are a "middle" size shop ... 200 concurrent jobs running during slow hours. There are no big solutions, just SAS analytics.

Each running node has the overhead of grid processes running on it, so fewer nodes with more CPU would have a higher total CPU available for jobs.
