It all comes down to what you are going to be doing. While hyper-threading isnt always being used it is nice to have. Also there are some features that are enable for the Intel® HD2000 graphics on the Intel Core® i3-2100 but these are only useful if you are using the IGP. So it really comes down to the price, graphics and hyper-threading. http://ark.intel.com/compare/53422,53493
