View Full Version : Buying a G5 2.5 - graphics card options

Just got a great deal of a trade in for a new G5

Can I get by in LW with the standard ATI Radeon 9600 XT?

I have two monitors a 17 inch Formac LCD and a smaller 15 inch crappy one, and I can't change the card it comes with.

So...

I'm wondering if LW will clog if I use both monitors together?


Any help appreciated, as I don't have much time to act!

The 9600 is capable, but pretty much a crap card. If you want decent 3D performance, I'd step up to at least the 9800. The 9800 gets great performance and stacks up pretty well against the newer cards like the 6800 and X800, considering its age.

So will I see an significant improvement in LW if I went for the 9800 over the

I'm really want to squeeze as much Display performance as I can out of LW - as I'm doing mostly Character animation.

So I might opt for the 9800 and guy 2 Gig of Ram, rather than 4.

What do you think?

Sounds like a good deal. I noticed a huge leap in overall performance when I got a nicer card (from the aging stock 9600). The more texture memory you get, the smoother image you'll get. Bear in mind that Lightwave's OpenGL performance isn't the fastest...but it'll be more noticable in other apps.

When the machine I use LW on got bumped from a 9600Pro with 64 megs of VRAM to a 9800 Special Mac Edition with 256 megs, I barely noted an OpenGL performance increase at all (well, aside from in games, obviously), even on hundred thousand polygon models. Maybe LW's OpenGL is CPU-limited? That machine is a single 1.6GHz G5. I guess 2x2.5 might put the graphics card to better use.

2 gigabyte is probably enough. You can check if you need more RAM by looking in the Activity Monitor. Under the memory tab, look on page ins/outs. If outs is half of ins or greater, you need more RAM, essentially (or something such, mabe it was 75% or more). ;)

On the other hand, if you get the 9600XT, you can always sell it later on when you do upgrade the video card.

Thanks for that. I went for the 9600 XT.

At last, I'll be the proud owner of a G5 - after a Jurassic amount of dithering!

I'd still consider getting a better card than that, especially with the discount Apple gives you on the purchase of a new system. You can't give away 9600's on ebay...I've tried. :D

True, Lightwave may not be much speedier on a better card, but the increases in apps like Maya, modo and C4D are pretty noticable, if you should ever decide to look around.
