I did the UD5 board from Gigabyte as well has the GeForce 560 Ti. I'd definitely go with a hackintosh. Having the ability to run any OS under the sun is nice. No 3D in the foreseeable future.

GA-Z77X-UP5 TH Thunderbolt Ivy Bridge board with some potential. Upgrading to ML and this board on my Customac this week.

I have a 3930k on a asus x79 sabertooth motherboard. Nvidia 560. No problems. Tonymacx86.com is your friend.

Also for a laptop, dell xps 15 quad core works, but only with intel integrated graphics, (no support for 525m) but other similar laptops have discrete graphics working.

@markmark1 Does your machine have sleep issues? I've heard x79 based systems have DSDT issues.

I got a working Hackintosh for over 5 years now, recently upgraded to the i7 2600k GTX260 and 16GB DDR, runs buttersmooth.

At first my mobo's USB3.0 wasn't working, fixed now. And a weird glitch with the ethernet port. My macbookpro and hackintosh can only communicate over ethernet if I boot the hack with the cable connected on both ends. Have to check whether that's resolved with my latest update.

Apart from that in the process of installing and tweaking there were quite a few steps to take, like a wrong ethernet kext (driver) was causing a kernel panic, had to tweak the BIOS a bit to get intel speedstep and turbo boost working, finding the optimal SMBIOS for my system, deleting a kext that was preventing that SMBIOS from booting, and more. Also with past multibeast/chimera/OSX versions I had to test and tweak my DSDT a lot before my graphics card was fully functional (all display outputs, acceleration, etc). In more recent versions it's recognized automatically by chimera.

All info for fixing these things can be found on the net. It just can take a while before finding it. Choosing hardware that has been tested by others before is advisable.

A minor glitch that I'm still having is the USB2.0 ports on my firewire+usb PCIe card not working. Firewire is working and I have enough USB on my mobo so I don't really care.

@soundgh2: Thats cool. I'm using PT&Reaper. What Motherboard?

Right now, still doing research. How much more do you really get in the real world with PT/3D/Video with the Xeon2687's? The overclocked 3930k looks to be excellent price/performance. I think that may be the way to go for me.

@artiswar You shouldn't be having problems with Sleep in ML. Remove Sleepenabler kext as you dont need it anymore. All kext extensions now run from system/Library/Extensions. There's also no more 32 bit mode in ML so be careful about using any old 32bit kexts to 'fix' things.

@artiswar: How about this one?

I went the hackintosh route

dual booting fcp studio 3 and fcpx

Z77X-UD5H, core i7-3770, 16gb ram, sapphire 6870 delivered 3 network projects so far at lightning speed!!

Guys, what do you think about instructions to make dual booting hackintoch, so all Mac system will be located on external USB 3.0 drive?

Btw, to avoid misunderstandings, installing on a USB drive doesn't mean any PC can now be booted with this OSX install. The tweaks required in order to make a system boot and run optimally are highly system-specific, so the chances of successfully booting a random other system are quite slim.
