I currently run simulations on an IBM x31 Thinkpad (laptop), with an Intel Pentium M, 1.3GHz processor. I am planning to buy a desktop to help speed up my work, but I am wondering if R is compatible with some of the newer technology that has come to market (i.e., Intel Core 2 Duo, Quad Core processors, 64-bit operating systems). Does anyone know the threshold or limit on R's capabilities, where buying "more computer" ceases to impact the speed at which R executes its task at hand? I need to know what type of processor, how much memory, cache, etc., I should be looking for in a desktop.
