This is my iMac model. 2.93ghz i7 2010 iMac 4gb ram (EDIT - right now it is 2x2gb sticks in the bank0/bank1 and I have two additional slots left) iMac 11,3 - Model Should I upgrade and buy these two 2 x 4gb ram sticks for my iMac? Are these the correct memory sticks for my iMac as well? Is the price pretty good as well? I will be doing some film editing in the near future and I'd think the ram would help? http://www.memoryexpress.com/Products/MX35470 2x4gb stick http://www.memoryexpress.com/Products/MX42988 1x8gb stick What memory stick is better? Same price so should I get the 1x8gb stick so I have one slot remaining on my iMac to upgrade? I've never upgraded ram before. Will I see an increase in performance dramatically? Thanks.
