How to upgrade OS X

[MrVegas]

I'm rather ignorant about OS X. I have an iMac with 10.5.x.

I want to upgrade to Snow Leopard or Lion. Can I go straight to Lion? On the Mac online store it says you can download Lion for $29 but you have to have Snow Leopard first.

You'd have to have SL first, then Lion...assuming your iMac supports either one.

 

[MrVegas]

how can I tell if my iMac would support SL?
