I use a GTX 580 3Gb both for display and rendering. It works very well with Cycles for rendering but I would like to buy a graphic card only for display and with good performances in viewport (sculpt, particles etc…). It seems Quadro are overpriced and I don’t know anything about ATI cards but from this thread, they seem to do the job. What card could you advise me please, no matter of price for the moment (the best and the the best quality/price for example) ?
If it’s only for display and only for Blender then you probably don’t need to spend more than 1000 $ on that. Quadro and Firepro are made and their drivers are certified for CAD programs mostly. http://www.youtube.com/watch?v=fut7m4Q-7W8
Blender will NOT take advantage of that kind of power but if you use Blender in combination with other programs that do then it’s a good idea to invest.
I own and use a 7970 with Blender, and it works great in Blender. Selection of objects in scenes with high poly counts is fast. Sculpting still is quite smooth at almost 40 million quads, though the viewport orbiting lags at that amount of polys.
Textured mode is quite bad, though. Solid mode and sculpt mode work well.
Blender’s viewport is in need of an update - both for visual quality (especially textures) and speed. Having said that, Compared to Modo and Lightwave I feel it competes quite well. SoftImage: no competition there, SI rules.
Yes, I saw this an other of your thread ;). In fact, if I was sure that both the 2 GTX 580 and the HD 7970 fit in my case without touching each others and have enough room not burning when rendering, I take the HD 7970. I could sell my 2 GTX 580 and buy a Titan so there’s space between the HD 7970 and the Titan. The Titan performs as well as 2 GTX 580 excepted its has 6 Gb of VRAM. But that’s make more money to spend.
Also very handy when sculpting at very high (over 30 million) polygons, since sculpting details is still quite smooth, but orbiting the view is very laggy: turn on fast navigate with boxes.
I’m gonna give it a try.
And please check the forum, because I made a video to proof smooth sculpting at 20 million polygons or more before.
Ok, if I don’t find it, I’ll come back to you.
Also, how far do you really need to go with sculpting? More than about 20 million polygons should not be required generally for the detail needed. Most of my sculpting is lower than that, especially now that we have dynamic topology.
