Don't EVER buy OC edition cards. They're unreliable, or at least subject to problems. Most of the time it's not worth it anyway, buy a non oc card and overclock it if you want but you're asking for trouble with an OC edition card. They always mess up with the memory chip quality, condensators or cooling system to lower costs and get better cuts...
I'm sure we could draw a direct relation graph between OC cards/normal cards and artefacts/card failures.

I respectfully disagree. OC cards cost a bit more because they have higher quality memory (that the Manufacturer knows CAN/WILL handle it) and they generally have FAR superior cooling. The great part about that is, the aftermarket cooling that they install makes those cards silent. Most of these cards have a pretty lengthy warranty too

I would never buy another reference card and OC cards are the ONLY way to go, in my experience...even if you never overclock them. If Andrew would ever update CUDA and expand it's usage to all sculpting and painting tasks, these new Kepler cards should rock in 3D Coat. 3 times as many cores as my 400 series!

Im not really sure if the graphicscard will boost some speed in 3DCoat, few months ago I switched from a GT330m to GTX560Ti.. I dont really notice a big difference.. :(
Only difference is that I have more voxels/poly's on screen.

Im just wondering.. do any of you happen to know if Andrew is working on CUDA updates?

Pretty sure there's alot of speed to gain in this area.. :)

为什么我的只能设置32个cuda内核参与运算

GTX690
3930K 32G2133RAM GTX680
