At work we use SAS to manipulte large amounts of data everyday on our workstations. To give an indication of scale the largest merges we had to do was merging 24 files of 2GB in size each together into one big file (if you are familiar with SAS the files are binary compressed too!). If we upgrade our PCs to core i7 then which of Core i7 975 or Core i7 960 is better? The main difference between the two seems to be QPI. So does that affect large scale data processing such as merge datasets in SAS?
