Yosemite troubleshooting need


Hello, for the last few days I have been struggling to install Yosemite on my AMD PC. Now I have installed it, updated it to 10.10.3, and using 10.10.3_SSEPlus_V2 kernel because it fixes some problems i had on 10.10.1 (like pink icons, Safari/iTunes crashing and App Store not downloading anything). Now it runs pretty good, except a few things which just test my nerves.

1. Sound is cracking, before and after 10.10.3 update, after the 10.10.3 update i reinstalled my old audio kext because i had no sound, and the problem is still there

2. System boots in almost a minute, i have no idea if it's normal or not, maybe it's because it's running on AMD etc.

3. My video card is seen as ATI Radeon 5000 instead of 5770, and sometimes it looks like the windows while dragging them, lag a bit, also i can't get my Philips 21:9 monitor to work on native 2560x1080 (i use switchresx now but with the config i am using right now i can only get 51hz refresh rate)

4. I also have a homemade USB Webcam from and old HP G60 laptop which from what i can see it's recognised because the LED from the webcam turns on when i open FaceTime, but there is no image and FaceTime just hangs on a black window)

I'll try to post my complete PC configuration below and also the System Report i get from About this Mac.
