Help with Lion on P8P67 LE with Core i7 Sandy Bridge

[War Machine]

I really need some help, and simply cannot figure out how to proceed with the Lion installation. This is my very first attempt at this.

 

Using an external USB drive I was able to install Lion on my PC using "Chameleon RC5 752 Lion+Snow" to boot the drive, and "Extra Lion DP4" to fill in the missing files. This process works but the computer is runs slowly during and after the installation. The main problem comes afterwards when I try to install Chamaleon on the main drive and try to put in all the correct kexts and whatnot. Whatever I use just renders the drive unable to boot from. What I need is some advice or just someone to point me in the right direction because pretty much every guide I've read assumes that you got the post-installation part figured out already (and I obviously don't) or that the installers they use match my system specs perfectly.

 

So, aside from Chamaleon to make the drive bootable, what other installers do I need for my system?

 

My specs are:

Motherboard: ASUS P8P67 LE (REV 3.0)

Processor: Intel Core i7-2600 Sandy Bridge 3.4GHz

Video Card: MSI R5770 Hawk Radeon HD 5770 (Windows simply recognizes it as "ATI Radeon HD 5700 series")

 

Again, I just need advice on what installers or files to use for post-installation cause everything I've tried fails when I attempt to reboot. I'm thinking maybe I am using the right files, but just missing something else, I don't know. Any help is greatly appreciated.
