I'm about to purchase a 2010 Mac Pro and I'd be grateful if anyone could offer some advice.

I use jitter/Open GL for 90% of my work mainly real-time video input.

I've also written a few patches utilizing standalone apps for use with multiple cores, never more than 3 for one patch.

The 4000 is over double the price, price/performance realistic for jitter?

- Two 2.4GHz Quad-Core Intel Xeon “Westmere” (8 cores)

I have a 3.33 6-Core with a Radeon 5870, and Jitter/OpenGL performance is very impressive. Not sure what the Quadro would add because I've never tested it.

I think the higher clock speed with the 6-Core will make a difference to you, enough that it's the better option than the 8-Core. The 8-Core does have twice the memory slots if that's important to you.

Go with the 6 core and the Radeon. That's what I have. The higher clock speed outperforms even the 12 core models in many applications. For Jitter, you'll generally want to use the cheaper gaming cards like the Radeon, which are made for speed; rather than the pro cards, like the Quadro, which are made for precision in CAD applications.

Nvidia Quadro 4000?
