Well most modern motherboards for Athlon64 and Core 2 Duo can take 4
DIMMs, of up to 2GB each (if you can find them and afford them).  So
that is 8GB ram.

Opterons use (at least on the 2xx and 8xx series, not sure about 1xx
anymore) buffered memory, which allows them to run more than two DIMM
sockets per channel, although at a slight latency penalty.  So the
ability to use more ram is to do with the memory controller and the ram
being used on opteron systems.  Both cost more than the stuff you would
use on a desktop machine.

Currently the Core 2 Duo chips are what I consider the right thing to
buy, being that they are faster than the AMDs.
Thanks, but suppose that I don't have enough money to buy the Core 2 Duo barebones box at £350 ($700) but I can afford an AMD Sempron 3000 box at £139 ($280). Would you prefer the AMD Sempron over a similarly priced Intel Celeron 2.8 GHz?

For little more $320 I could get a Pentium P4 box OR for a little more $350 I can get an Athlon 64 3500 box.

(The prices and choices are on the novatech web site) www.novatech.co.uk

Your opinions on the best box are appreciated.

The Pentium 4/D was
never on my to buy list.  The athlon 64 used to be, but now intel
actually seems to have done something right again.
