I use a Nvidia Quadro NVS 290/PCIe/SSE2 at work with dual monitor setup. Since 11.10 things has gone downwards with performance.

But now with 12.04 performance is even worse, and I can agree that the 290 is old and puny.

So when I look what low profile cards I can get to my computer today, the choice it Radeon HD 6570 or NVIDIA Quadro 600.

I have always used Nvidia on linux beq I think that historically their drivers worked better. But which one do you recommend today on 12.04 and Unity3d?
