Dual Core Processor

We are in process of moving to 64 bit HP servers with sql2005 standard
edition. We were just wondering which is better option, to get a server with
2 dual core processor or to get a srver with just 4 processor? How does
SQL2005 handle the hypertheading of dual processor?
Thanks,
CarlosDual core processors and hyperthreaded processors are totally different
things. Hyperthreading actually adds a "virtual" core, and is not leveraged
very well by SQL Server. Multicore processors, on the other hand, actually
behave like multiple processors -- two cores gives you two processors worth
of power. The great thing in terms of SQL Server licensing is that you only
need to pay per socket, rather than per core. So buying two dual core
processors will save you a substantial amount of money over buying four
single-core processors. And now you can buy quad-core processors, so why
not just get ONE of those?
