Hi Hakcintosh Community !
I hae succesfully installed Hackintosh once beofre on my Dell Computer about a year ago but because the wlan wasnt working properly it wasnt really worth keeping it on there, I only used it for iMovie etc....

My question is which OSX (Lion, snow leopard etc..) would work best and would run lag freeest (?!) with my Computer specs and if it would even be possible because I have heard that with AMD it is harder than with i5 etc....

Here are my Computer Specs:

2.8 GHz AMD Phenom II Dual-Core Processor N620
500 GB SATA Hard Disk Drive 7200 rpm
4 GB DDR3 (2 x 2048 MB)
ATI Mobility Radeon HD 5650 Graphics (switchable)
SATA optical drive: LightScribe SuperMulti DVD±R/RW with Double Layer Support

Any Help would be greatly appreciated !

What is the easiest way to backup al my Windows Stuff as I am aware that if I want to install MAC OSX86 Ill have to partition my Harddrive therefore deleting all my Stuff on my C: Drive ?!?!?!
