Howdy all,

I know this question pops up quite a bit, but I swear, it's different this time. :P

Do I go Radeon HD or Nvidia?

I am looking for something less for gaming, and more for handling some pretty hefty CAD, GIS, and some 3D graph/map rendering functions. The only gaming I see myself doing is maybe Morrowind in WINE. I am a PhD student in archaeology, so the 3D stuff has nothing to do with software or game development, should that make a difference. I would also love to run dual screen at some point soon.

I am not averse to shelling out a little bit more than I initially wanted. I am thinking under $200, and under $150 is even better. Here's a couple of thoughts I had:

GTX 560

or

Radeon HD 6770
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102940

or

Radeon HD 6870
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102948

Is this all overkill? I am fairly new at this. I built the box back in September, but it was my first. Also, I have only been using Ubuntu since July on a regular basis (it is now my sole OS), so I just don't know how seriously to take all the Nvidia or Radeon hype/hate.

Thanks!

I'd start by narrowing your search to professional graphics cards because they're designed for CAD and 3D modelling.

Next, you want at least a Gigabyte of memory, preferably DDR5.

Finally, you want it to have the latest OpenGL and DirectX revisions for maximum compatibility with programs.

Optionally, my experience from building casual/gaming computers says that Nvidias run hotter than their ATI/AMD counterparts.

Combining all those factors points me to this card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814195096

Plus one of the reviewers says it works on his Linux machine.

However, the specs indicate that it's a HD 5670 that's had its code tweaked for professional applications and had its price doubled. (The performance differences aren't huge and crossfire was written out)

With THAT in mind a standard HD 5670 starts at $70 or you can go for the middle ground for price and get a performance boost with a $110 HD 6770.

If the upgrade isn't urgent, I'd wait a few months for the 7000 series.

PS. (I owned a 5670 and upgraded to a 6770. Both handle most of my 3D games at max settings. ;3)

Thanks Fennecat!

This seems like pretty sound advice to me. The only thing I can't do is wait too long, though I am not adverse to upgrading to a 7000 series a little bit down the road. I think the 6770 probably sounds about right.

I wouldn't recommend waiting for the 7000 series because, when it is first released, it might not work on Linux.

Good advice, thanks!

If you do WINE gaming, then go for NVIDIA. WINE Developers only test with NVIDIA and the proprietary driver has a much better reputation over AMD's when it comes to this.

If you aren't going to do anything with WINE, then the 6770 should be just fine.
