I'm about to upgrade, and I need a solid system that's as future-proof
as possible. Applications? Mainly business graphics (autocad and
such), and digital stills and movies, with the usual spreadsheets and
word processors. Some gaming, I guess, but that's not a biggie.
Whilst money _is_ important, something that will serve me as far into
the future as possible is more important.
So...
If you had your druthers, and a good budget, what would you put into
a rather nice if a bit dated full tower if you were me?
The future ain't what it used to be
The thing is, we are on the edge of a transition. DDR2 memory
is coming, 64 bit computing with different sockets for processors,
PCI Express instead of AGP for video cards, BTX form factor
motherboards, and so on. If you buy a board now, it is at the
end of the current generation of stuff - this is particularly
bad if you don't currently own a good AGP card to put in this
system you are buying. If you buy an expensive AGP card now,
when the next systems come out, there won't be an AGP slot to
put it into.
I guess whether you'll be happy or not, depends on your point
of view. My rule of thumb is "don't upgrade until you can
double the performance". By that rule, if you buy a P4C800-E,
the P4 socket 478 of your choice, a ATI9800XT or an FX5950,
a big ass power supply, you won't need to upgrade for two
to three years.
In the AMD camp, there are the 64 bit processors (and two
different sockets for them), offering similar or better performance.
The difference with these, is the new AMD processors have the
memory controller inside the processor, instead of in the
Northbridge. This reduces memory latency, but it also means
you are a slave to whatever the limits of this memory
controller happen to be. Of the two AMD processors, one is
single channel (socket 754) and the other is dual channel.
The single channel processor takes two double sided unbuffered
DDR400 memories at DDR400, but slows to DDR333 with three
sticks. (See the K8V on the Asus site for details.)
The dual channel AMD FX processor (socket 940, to give the extra
pins needed for the second dram channel) uses registered ECC
PC3200 memory, something which is relatively new on the market.
PC2100 registered ECC memory has been around for ages (and there
is plenty of it), while the PC3200 registered memory is new,
because the faster register chips were created in March of 2003.
The Asus SK8V has four DIMM sockets on it, so you can install
more memory than the K8V. Since registered memory allows the
use of larger modules (the purpose of the register is to
buffer the address and control signals), you can use 4 x 2GB
of registered ECC memory. (As for the SK8N motherboard, you
might want to check whether the Hypertransport bug has been
fixed ot not - the Nforce3, at release, couldn't run the
Hypertransport bus at full speed.)
Have fun,
