Beepcake said:You can do 2+1, but it's recommended you do 2+2 (with only 3 addressable) so you can take advantage of the dual channel memory. Dual channel is nowhere near as important as it is on the shared graphics memory machines (MacBook, base iMac and Mac Mini), but you'll still take a performance hit if you don't match your sticks.
How much different will i see if i went 2 + 2 as it would be cheaper going 1 + 2 but i want to know if i would miss much... and if it worth wasting that extra for a extra gig that not being used
