But don't believe me or the other people who've seen the difference. Go buy the Intel box. No skin off my back.
To be more detailed... AMD Opteron has some specific technical advantages to their design over Intel when it comes to peforming for a database. Specifically no front side bus :)
Also it is widely known and documented (just review the archives) that AMD performs better then the equivelant Intel CPU, dollar for dollar.
Lastly it is also known that Dell frankly, sucks for PostgreSQL. Again, check the archives.
