Definitely, we just went through a quote with them, we asked for Opterons, they sent us a quote of under-spec'ed and over-priced Opterons, and super-spec'ed and under-priced Xeons and Power5s ;) > Sun is offering 2 way and 4 way today. That's what we'll probably end up getting, 4-way Sun Opteron, we got two 2-way Sun Opterons and they are very neat. > Same with HP.

I wonder how the new IBM 8-way Cell Processor (which is meant to go up 64-way) will cope with bioinformatics applications...
