Right? Shachar
If you're looking for a computation cluster, I'd wait for for the 1.8/2.0Ghz dual core Montecito core (which AFAIK, should be released in Q1/2006?).
However, it greatly depends on the release price. If the current price prevails, it's cheaper to buy a quad dual-core Opteron then buy a quad single core Itanium; No matter how fast the Itanium's FPU unit is, I doubt that a 1.5Ghz core can outperform two 2.2Ghz cores...
However, before you choose, I'd also take a look at IBM's power4/5 systems. At least from a design perspective, their multi-core design is top dog.
As for database (or any other Integer intensive applications), I'd go with an IBM/HP dual-core Opteron based machine. Without doubt.
Considering it's price, an Opteron 165/265 is simply a steal.
