View Full Version : nVidia 5700 ultra and 5900 questions

10-07-2004, 04:04 PM
I'm looking for the nVidia card, 5700 ultra or 5900, but the power requirement of both cards needs 300 W up. My machine has only 266 W with two DVD drive, one HD. Is there anyonr out there using those in low PSU?
Also, does 256 MB and 128 MB matter fir LW?

I doubt you'd find a 5700 Ultra or 5900 with lower power requirements than that - both cards have a molex connector 'cause they need the extra juice. I think the 5200 may be OK but it's not exactly stellar. Either upgrade your PSU or go for a GeForce4 Ti4600 - that'll still work great with LightWave.

As far as the video RAM goes - all of my GFX cards have had 128mb of RAM (or less) - I think 256mb may be excessive for LightWave use (unless someone else knows different...)

I'm using a 5900XT, and my PSU is a 460W one. Frankly, I wouldn't want a less powerful PSU; I've burned them out before now, by pushing the PC too hard for it to handle everything, so I will always play it safe now.

Thanks guys,
I think I might be able to use 5700, but I also have the other software that really require OpenGL power. So, I might go with QuadroFX500 because typically, it about 5600 series, but with benafit of hardware openGL.

When I bought my PC it had a nVidia 6800 ULTRA in it. Then I started seeing some odd things happening, so I sent the card back and they sent an nVidia 5900FX as a replacement until they could find a new 6800, that is working fine (they STILL haven't found a replacement!)

My PSU is 400W, despite my constant asking if it was powerful enough as ALL the reviews I read said give the 6800 at least a 480W.

So, I wait until they find a 6800 ULTRA. If when I get it back it still has problems and it's because of the PSU I'm really not going to be happy.

I told the shop I wanted a more powerful PSU, but they insisted 400W would be okay.

My advice - get a big PSU, it'll save you no end of trouble!

And spend the extra money to get a GOOD power supply. Antec is pretty good.
