Hi all, This will be my second build. Primary use is as a work desktop slanted for statistics and GIS. I have some parts already (DVD drive, OS, monitor, GPU) and budget is around $600. I am NOT planning on buying everything at once, but over the next month or so. I'm looking for this build to last at least 5 years, with the possibility of its primary use changing after the wife finishes doctoral program. I had originally thought to go with an i5 to reduce costs, but am guessing that GIS (ArcGIS 10) will benefit from a better processor with hyperthreading capability.

I've used Corsair previously. /EDIT) I know some of this is going to push over the budgeted amount, but I'd rather go a bit over for quality that will last longer. Advice is gladly welcome. Thanks in advance.
