Re: Hardware Recommendations

The dual AMD board(s? I only know of one..) are *really* new, so I'd be
careful.... They sure do look nice though and aren't that expensive compares
to those quad Xeons...

A Note on Disks :
I respectfully disagree with Steve's "disk speed isn't terribly
important" -- it can be (and is totally dependent on what you're doing) and
since you have the on-board U160 with all the dual Athlon boards I've seen,
you might as well take full advantage of it.. That and you know Seagate has
those new 15,000 RPM U160 drives out *evil grin*..

A note on RAM :
Note that those dual Athlon boards take registered DDR RAM, which is a
little more expensive than your run-of-the-mill SDRAM (about twice(ish) as
much according to some numbers I just looked up). I wish I had something
going that needed that much horsepower so I could justify buying one!

Good luck!
