I have 2 x 2GB and I want to upgrade my memory. I can afford either 1x8GB or 2x4GB.
Do I need the same size in both modules like 2x4GB? Or I can keep one and replace the other one: 2GB + 8 GB for a total of 10 GB?

What's the best option?

Same size modules perform very slightly better but are by no means a necessity.

My Mac Mini has run fine with 5 GB of RAM for the past three years; a 4 GB stick along side the original 1 GB. Others I know also have unequal RAM stick pairings, in various Macs, with no problem.

Equal paring may be optimal, but it is not essential. Go for the 8 GB stick, and get a total of 10 GB RAM.

This topic has been discussed many times on many forums.
 
Add the 8 and at a later date add another if you wish. The performance hit with mixed dimms is negligible
