AGP Graphics card for older PC to improve YouTube?

[Iggy]

Ideally you want a card that supports UVD so HD2000 (apart from 2900) series upwards.  AGP HD2400 can be bought fairly cheap but I understand that you need to apply certain tweaks to the registry for certain files.  HD3450 might make more sense if you can find one decently priced.

I'd second this latter approach.
I have R300 cards all over my work area as I have been using them for MorphOS machines, but I'd going with at least an HD2000.
That gives you Direct X10.1.

At one time, I had an AGP HD3850.
That was a simply wonderful card.
The 4650 is also available as an AGP card.
And your cpu is more than powerful enough.
Until recently I was using a single core Opteron operating at 2.2 GHz and only recently upgraded to a dual core at 3.00 GHz, both were adequate.

Best cheap DX9 card?
An AGP X800XT would be good.

ATI Radeon X800XT All In Wonder AGP $35 plus $10.29 shipping

AN Nvidia 7800GS would also work.

I still use a P4@2.53 GHz with 2 GB of RAM and a Nvidia 6800 GT AGP Video card and still runs Youtube movies without a problem.

Nvidia 7600GTs can be had without a secondary power connector for AGP systems.
As to cards without a cooling fan, you won't find very many powerful cards set up like that.
And a video card's cooling fan is not particularly loud.

Indeed HD3850 is the best agp card out there.
But I don't think this is a matter or gfx card.
I have noticed that single core machines cannot play yt videos well anymore.
Try to disable hardware acceleration in flash.

Yes, what pocessed me that convinced me to sell my 3850 is beyond me.
Actually, I was using a single core Opteron until recently and thathandled video fine.
Not to take too many pot shots at thr P4, but that processor never really performed all that well.

[Iggy]

Nope Nik, you're wrong there.
I had a 3850 AGP card (it exists - there are a few on eBay right now), the performance is a little smoother than the 4670 or 4650.

[Iggy]

I was not aware that they were not using FLV on some videos.
That is actually an improvement.
MorphOS can handle MP4 format.

And frankly, I'm sick of Flash.

[Iggy]

On that we agree!

"Flash sucks!"

[Iggy]

All this tells us one thing: Flash and HTML 5 suck big turds! Hurray for utterly brain dead standards.

At least HTML 5 is an open (turd? did you actually use that word?)...standard.

And when its done right, its much more efficient than Flash.
I have a 1.42 GHz iBook that flies when showing HTML 5 encoded material.

Why are we still allowing Adobe to extort us?
Didn't we learn when they tried to bend Apple users over a barrel with postscript.
They are worse than Microsoft.

At least with Microsoft I have alternatives.

(btw - on alternatives, I could almost get used to Linux, Android use must have softened my resistance).

[Iggy]

Nope, it tells is that CPU driven video playback on a 2.8GHz Windows machine is worse than MorphOS running on a CPU half it's speed.

It tells me that the html5 code that Fab is using kicks ass.
But then, have you noticed how much better MorphOS is at play video than OSX?
Pretty weird considering we don't have the benefit of gpu acceleration (just really good developers).

[Iggy]

Alternately, there are Radeon HD4650 AGP  video cards that would provide acceleration and would work with this machine.

[Iggy]

No, you will see an improvement with a 5700.
Remember, what they are talking about is video decoding acceleration.
All 2D and 3D drawing functions will be better with that card than with i865 integrated graphics, so its not just game acceleration.

I don't have the advantage of hardware acceleration under MorphOS (the OS doesn't support it) and I still favor more powerful video cards (and I don't play games either).
