I have a VPCEB190X laptop with
*Intel® Core™ i5-520M processor (2.40GHz) with Turbo Boost up to 2.93GHz
*ATI Mobility Radeon™ HD 5470 GPU (512MB VRAM)
*4GB (4GBx1) DDR3-SDRAM-1066
*Atheros build in b/g/n
*Realtek sound card
*500GB 7200 RPM Hard drive
and its running windows 7 professional 64x.

Would i be able to install snow leapord with these specs and also would i have to format my hard drive if i want to install snow leapord? or is there a way i can partition it and not lose my windows 7 pre-install? Is my laptop compatible with mac osx?

Thanks in advanced.
