color:#1F497D'>For video memory usage, the rule of thumb is to take the screen
resolution and color depth. For instance if you are running 1024x768 with
24bit color depth (3 bytes) then you would multiply them all together ( 1024 x
768 x 3 ) = 2359296 bytes or 2.3 Meg. If you are using double buffering then
you would double that amount to 4.6 meg. Most of the video graphics memory is
for storing bitmaps used in graphics intensive programs (like video games)
where images need to be rendered often and as fast as possible. Im not positive,
but im pretty sure that XFree doesn’t require that. It may store your
desktop background image in there, and the mouse cursor, and maybe even a few
icons. But that still wouldn’t take the 1024x768x3 past 10 or 20 Meg.<o:p></o:p></span></p>

I found that for the Intel G43 chipset, the graphics core can use up to (and

<p class=MsoNormal><span style='font-size:11.0pt;color:#1F497D'>It could be
because onboard graphics share memory with the system. For instance, if
you had 512 Meg system RAM and used the onboard graphics card configured to use
128 Meg then it would only let your OS access 384 Meg. The thing is,
unless you are planning on running games or a program that needs to preload a
bunch of bitmaps into video memory then you really donąt need a lot. Im
currently running my redhat box with a 32Meg card and id bet that half of that
is probably collecting dust doing nothing.</span><o:p></o:p></p>

I don't think any boards are immune from the slot usage issues.... <br>
<br>
unfortunately the good old PCI slot is in decline .. but there isn't much by
way of PCI-e soundcards at the high end part of the market (except for MOTU
which has all but declared war on the linux user, so I don't think that is any
option... ).... and firewire support is very limited ....... so I guess looking
for PCI slots is important... <br>
<br>
Steering away from onboard graphics is important for music production unless
you are going to pile on the RAM... If the cash is available I'm starting to
think that the SSD disks would be the best option... .for both speed and
silence.. and from what I have read they scale very well in RAID configurations...
but that is getting seriously expensive for the moment.... and would
require some additional storage space (1TB USB drive as external
storage that can be unplugged while working on music to reduce background
noise....)........<br>
<br>
as for CPU as Geoff said .. Ardour is very economical on gentoo.. the rest if
up to plugins.. how many you want to use and which ones... I'm still not
sure about the quad core vs less core argument.. <br>
<br>
As Paul recently pointed out on the forum as audio processes are
mostly linear (not parallel) I don't think it shouldn't make much
difference how many cores you have...... when running Gentoo more cores is
definitely nice (all that compiling) ..... I would wait a couple of months
and see how the core i7 pans out for linux and audio performance... original
Nehalem write ups said you could disable cores for gaming to
increase clock speed (I imagine via the BIOS)... which could work well for
audio until everyone starts writing for multi-core ... <br>
<br>
maybe AMD have something new in the pipeline too.. but the triple core
phenoms look like extremely good value... <br>
<br>
<br>

<p class=MsoNormal>I second the vote for Gigabyte boards as being reliable and
linux-freindly. I bought one about a year ago after posting a very similar poll
on this list! However mine has one slight isue which apparently is a common
flaw - it would randomly and falsely think it had detected me inserting a CD
into the IDE CD-ROM drive. Switching to a SATA unit and disabling the IDE
controller solved this.<br>
<br>
As others have said, think very carefully about the number and type of adapter
cards you will want to fit. My board has a PCI-E 16x slot for the graphics
card, and I duly bought a huge NVidia card with a great heantsink on it - only
to find that this then obscures the slots either side because they're so close
together. I would always assume now that if a board has a mixture of PCI-E and
PCI slots, that you will not be able to fill them all. <br>
<br>
So, Gigabyte gets my vote as reliable and fast, but not for being particulalry
cleverly designed. I hear great things about Tyan boards all the time. <br>
<br>
One thing to be really aware of is to steer well clear of anything with VIA
chipsets on it. There's even a statement somewhere on the Ardour website saying
this, and I can say from experience that if you have any VIA stuff anywhere on
your motherboard then you are not going to achieve low latency however hard you
try.<br>
