Rocco,
I was in the same boat as you were, stable 10.7.4 system but a software update forced me to move to 10.9. Plus, I sort of like Mavericks now that I've gotten used to it. I also have dual monitors, which Mavericks has better support for. I suggest unless you have a specific reason for upgrading to 10.9. Stay with 10.7, because following the method below, you can't go back. Note that not all 10.7 applications work on 10.9 so check this before you start and you should read up on 10.9's security features before upgrading, especially how gatekeeper works. Some people have also had trouble with iMessages on a Hackintosh under 10.9.
In all, I found that after the update, sleep works a lot better. Restarts are faster and performance is on par with 10.7. Although like you the network still gives me trouble from time to time, forcing me to reboot the machine. Good thing we both have SSDs.
You'll need to upgrade the BIOS to UE1 which is the trickiest part of the upgrade. Your system is almost identical to mine, except I have a HD5870 graphics card whereas you have an HD6000 series. I'm fairly certain that the HD6000's are supported in Mavericks but it would be best to verify this before you start.
Here's what you'll need before you begin (be sure to backup to timemachine as well, just in case). Having two computers or at least an option to access the web while you perform the upgrade is advisable.
1. Read through the Mavericks install instructions at
http://www.tonymacx86.com/374-unibea...-based-pc.html (Install STEPS 1 - 5)
2. STEP 1: Download the recent version of Mavericks 10.9.3 so you only have apply your multibeast settings once
3. Prepare a 10.9 USB boot drive using unibeast following STEP 2 of the installation guide.
4. Download a recent version of multibeast and have this available on one of your hard drives
5. In Windows, download the new UE1 bios -

6. In Windows, download rufus
http://rufus.akeo.ie to prepare a DOS boot USB drive so you can upgrade the bios
At this point you are ready to start. Once you begin your computer will not boot into OSX until you finish the upgrade.
First, from OS X,
rename /Extra to /OldExtra as the UE1 BIOS does not use DSDT files and will cause problems booting.
Next, upgrade your bios. You can follow this video
http://www.youtube.com/watch?v=D-FcRUp2A-E or read the DOS Flash utility instructions at
http://ca.gigabyte.com/webpage/20/HowToReflashBIOS.html. Configure your UEI bios using the settings from the 10.9 installation instructions (e.g.):
1. To access BIOS/UEFI Setup, press and hold Delete on a USB Keyboard while the system is booting up
2. Set to Optimized Defaults.
3. (Optional) Set X.M.P. Memory Profile to Profile1
4. If your CPU supports VT-d, disable it
5. Save and exit.
Now, you are ready to upgrade to 10.9. Follow the upgrade instructions under STEP 4: Install OS X Mavericks of the 10.9 install guide. (
skip item 6 on formatting your drive and just perform an upgrade of your existing system).
Last, follow STEP 5 from the Installation guide. Reboot into OSX Mavericks using the USB drive and choose the Mavericks installation. Apply your settings or you can start from my settings file posted earlier in this thread. Some options have been replaced in the newer version of mulitibeast but you can at least see what is working for me.
Reboot and enjoy mavericks.
Feel free to send me a private message or post an issue in this thread. Both go to my email, but I don't usually check email after 6pm pacific time.
