How much difference does it make? thankyou For chess programs, you will see almost nothing that would justify the tremendous price difference between Xeon with 2MB and a PIII with 256KB using RDRAM-800. Xeon with 2MB L2-cache make sense should you plan to build a system with 4 or more CPU's. Otherwise, they are just a waste of $$$. You can get more info regarding performance from SPEC INT95 (http://www.spec.org/osg/cpu95/results/cint95.html) and look at Dell's 610 vs. Dell's 410 system -> Xeon II vs. PII. At this point in time for SPEC INT2000, Dell is mainly submitting performance data for non-Xeon systems. However, there are applications that _greatly_ benefit from this larger cache. I do not know any chess program that does for systems with less than four CPU's. This is not true for multi-processor systems with many CPU's. Gregor
