Hackintosh is laggy and slow

[studiosecond]

Specs: i5 (quad core)
Ram: 4GB
GFX: ATI 5450 (Display @ 1920x1080)

Could someone point me as to why the desktop is so slow

Launchpad and Mission control is a disaster...well...it loads up at 3 frames per second
Doing anything is just awfully sluggish.

I have the istatmenu app open. It detects all 4 cores and usage is all correct which leads me to the GPU...

Any ideas?

Which Mainboard are you using and which OS? 10.8.2?

i have the same problem on my Acer 8930 on 10.8.2 . I think the solution is a proper SMBIOS file , suitable for your specs. i fixed this problem in lion with a random SMBIOS but in ML i can get one to work ..
