Hello! I've placed an order for a mac pro 2.66 and in eager anticipation have decided to shop for memory. My goal is 16GB so I'm upgrading incrementally in 4GB (2x2GB) sets. Someone on a local forum mentioned MaxSink which are significantly cheaper than Crucial. I know absolutely nothing of Mac upgrades so it goes without saying MaxSink could be the cheapeast of the cheapest brand in existance and I would not be the wiser. http://www.maxupgrades.com/istore/index.cfm?fuseaction=product.display&product_id=157 $285 for 2x2GB set. Are they reputable memory or should I just spend the extra for tried and true, Crucial?
