I have an Apple Quad. Find me 10GHz of PC processing power for less, >please. I was not talking about Quad systems in regards to someone purchasing a new chess playing machine based on Paderborn results. I would assume most would be considering single CPU or dual core options as they are more reasonable/affordable in price. I think it is a very special situation in that a computer chess enthusiast purchases a quad machine specifically for chess. Consider the entry level dual core G5 2.3GHz for $2,499.00. For under $1,400 you can find a dual core X2 AMD A64 2.4GHz machine (for example: http://www.unitedmicro.com/cgi-bin/sysw.cgi?352204314) As far as your "10GHz of PC processing power", I think you will find that compared to an Opteron in chess, you are probably getting 8GHz at best, and probably closer to 7.5GHz. As far as price? The entry level dual, dual core G5 2.5GHz is $3,299.00 from Apple. If you assembled the Opteron system yourself, you could spend around the same amount or less. I didn't search the net for a pre-assembled Opteron dual, dual core system but I would imagine that if you bargain shopped, you'd be in the same ballpark on price (purchasing like components to the G5 setup and using Opteron 275 dual cores at the most, since I am quite confident that Opteron 280s would be 20%+ faster...) I have sent you an email asking for a benchmark of your system. We should be able to nail down a pretty good estimate of the difference between the G5 and Opteron for chess after I receive that from you. Regards, -elc.
