Well if you ever decide to, then Geekbench is the reference system benchmark util. Here's a list of typical mac benchmarks, and from what I read I'm pretty happy with my R830's performance in every way, it's really snappy as a 'mac' and with the new HDD it boots and runs apps lightning fast. A true macbook pro replacement for a fraction of the price.
I'm not using the SD card reader either so no real need for a (troublesome) kext install.
OK so kudos for Silvestr's DSDT & you for your hard work. It's a shame that sleep is not working - it'd be a near perfect hackintosh (still missing bluetooth) with it. It's funny that in my previous Qosmio I had bluetooth working perfectly but not so wifi and I had to change the mini-PCI card. Sleep didn't work either...but it didn't return a KP at boot time while using sleepenabler.kext at least. Hopefully someone will sort out this sleep issue...
I had some odd KP's while using a mouse connected to the USB3 port. No other KP since I've stopped using it. I'm using PXHCD.kext 1.0.8. Should I use other version instead?
Oh I forgot to mention I also experienced a weird crash (screen got all scrambled and freezes) the other day while using my headphones for a while listening to itunes music. Not sure if the problem was caused by the headphones being plugged in or just by using itunes for a while. I'll try to replicate the issue when I have the time.
About upgrading to 10.8.3 - well I did a fresh install. Instead of installing 10.8.2 I used 10.8.3 combo package instead and just followed your guide and it worked great! So no credits due here.
So now I've got an up to date hack without any serious issue. Yes I meant the AppleIntelSNBGraphicsFB.kext.
I've also tried to install the HWMonitor & associated FakeSMC plugins (I've used it before on other hacks including the Qosmio) but to my surprise the install didn't end well (returned a installation failed, contact your software vendor message, and after that it didn't boot any longer). Anyways not that much of a big deal really...
I've also upgraded my HD to a 750GB (need the space...) Seagate Momentus XT Hybrid drive and the R830 just flies! I'm able to boot in around 15sec in 10.8.3!
Try this kext is the one I'm using... version 1.0.11 (there's a lot in console log and you'll see a lot as well when booting in verbose mode, that's because they apparently forgot the debug loggin enabled..)
Sleep... well is not my strength we need someone to have a look at it, unfortunately it requires time to test which I don't have and knowledge about DSDT hacking which I don't have either... but since yours boots in 15" I guess is ok for you at the moment. If you want try to open a topic or research about it.. I think is not a super major thing to enable but needs someone that knows where to check/look.
