Thanks, I am going to redo the installer. I am going to try the suggestion made by Imkantus, as that seems right.

@MonkeyDLuffy I am not using a dsdt.
@Imkantus Thanks for that, i am going to try that AsereBLN booter.

EDIT:

I couldnt get my install dvd to boot, so i cleaned up my kexts directory. I found ATY_INIT and EVOENABLER (which i searched and is for 4700 cards) so i removed them. I also replaced my boot loader. Now in system profiler it says ATI Radeon 4600 Series, 512 mb (not 1gb) and that Hardware Info tool Imkantus suggested says ATI Radeon RV730, Quartz Extreme YES.

Also i am no longer getting the artifacts (line across screen every minuite or so). I am running through DVI 2 VGA at 1600 x 1200, which windows would not let me run at (max 1024x768).

Performace has seem to improved. Currently downloading Galaxies.etc

Should i upgrade to 10.6.3? What are the steps?
