Hi all,
Kind of had enough of Windows.

I have the following, am wondering what to do with the more-than-likely scenario that not all hardware will be compatible with OSX.

AMD Phenom X3 8450 2.1GHz
ATI Radeon HD4850
Asus M2N-68VM
4GB OCZ DDR2-800
1x WD 250GB SATA
- 150GB partition for OSX.
- 50GB partition for Windows.
- 50GB partition for storage.
2x Seagate 500GB SATA
- both for storage.
USB keyboard (have PS/2 adapter)
USB mice

I think there's a 4850 for Mac, but have not been able to find a driver so far.
Considering buying a Mac keyboard and mouse, will they work with OSX, hardware-wise?

Also, what are kexts?

Any help and advice will be much appreciated.

Best regards,
Nicholas.
