I was wondering about the backwards compatibility (the card being PCI-E 2.0)  I'm not losing any performance because the slot is 1.0 am I?  Also, any tips for installing card and PS?  Anything I should read up on while it's being shipped?  I will be asking about oc'ing after I get it installed and running normally.  Thanks again for all the suggestions.

My system:
Acer Aspire M5100
Microsoft Windows Vista (6.0) Home Premium Edition  Service Pack 1 (Build 6001)
