As far as i remember 3820 works even in SL but without power management and requires VoodooTSCSync on certain motherboards, and the old Quadro 4000 works great in 10.8 with Nvidia drivers.

 

What about the new 4820K and Quadro K4000? Do they have better (more native) support on Mavericks, or it would be a better idea to get the old 3820 and 4000 for a Mavericks based system?

 

Thanks in advance.

I have a 3930K and Quadro 4000 on Mavericks right now.

 

Power managment is getting better all the time on the SB-E CPU side, with 10.9, it's almost there, some reports say it's fully native in 10.9.2. But if you're building a new system, get the newer IB-E CPU, it'll be better supported in the future as it's the same architecture as the new MP's are running on. Read up on some x79 guides and go with the 4820K. If you can spare the cash, also seriously consider the 4930K, the two extra cores will help.

 

As for old vs new Quadro, the old one requires GE=Yes and some kext edits to get power management working. It's based on the GTX 400 series and it also runs seriously hot. The newer one is more powerful, based on the GTX 600 series, so in theory should be able to boot without GE=Yes and should have better support overall. Although that's only speculation based on what we've heard about cards like the GTX 680.

 

I was considering getting the K4000 a few weeks back, but shyed away because of the massive price tag. The downside is that you can get a 4000 used for a few hundred bucks, whereas a new K4000 costs the better part of a grand.

Thanks for the info. But does the new K4000 works OOTB, without the need to edit gfx kexts with every system update?

The best answer I can give is... maybe. I couldn't actually find an example of anyone building a hack with a K4000 when I last looked.

 

So in this case there are no guarantees, even though I have a strong feeling this card would work OOTB as a GTX 6XX would.

Well, seems like it works OOTB. Tested it couple of hours ago, still need to run some benchmarks to make sure everything is alright.

 

At the moment i have a problem with 4820K, i need to sort out the DSDT and for some reason VoodooTSCSync doesn't sync the cores properly...

Booting with the following kernel: http://www.insanelym...pic-fix-kernel/ because vanilla gives a black screen instantly.
