Hopefully someone can offer some insight to this memory dilemma I'm facing. I got the iMac Intel Core Duo with the standard 512 mb of memory. I knew I needed more seeing as I use Photoshop, Illustrator, Flash, etc... and now I'm ready to buy some. What I've found is that the Apple Store charges $300 for a 1 GB module of DDR2-667 PC2-5300. That seems a little pricey so I looked for alternatives and found this site: http://macramdirect.com/imac.html but there are two options on there. One for Samsung and one for a brand named MRD. I can get 2 GB of RAM for $250 if I go with MRD, or get 2 GB for $350 if I go with Samsung. So the question is: Is there a big advantage to getting the Samsung memory or would it basically just be paying for the name and the fact that Samsung is the brand of memory Apple uses? I guess it boils down to what would you all go with if you were buying memory. In addition if you have any recommended sites to buy from I'd be willing to buy elsewhere. Thanks to anyone who can make some suggestions and help me get my computer the boost it needs.
