*Can I extend Taka's question?* ** *Many of my programs in (mainly simulations in R which are cpu bound) on a year old PC ( Intel(R) Pentium(R) M processor 1.73GHz or Dell GX380 with 2.8Gh Pentium) are taking hours and perhaps days to complete on a one year old PC. I am looking at an upgrade but the variety of cpu's available is confusing at least. Does any one know of comparisons of the Pentium 9x0, Pentium(r) Extreme/Core 2 Duo, AMD(r) Athlon(r) 64 , AMD(r) Athlon(r) 64 FX/Dual Core AM2 and similar chips when used for this kind of work. Does anyone have any advice on (1) the use of a single core or dual core cpu or (2) on the use of 32 bit and 64 bit cpu. This question is now much more difficult as the numbers on the various chips do not necessarily refer to the relative speed of the chips. * *John
