Well, the good news is that I've found a good deal on a MBP on ebay and it is on its way. The not-so-great news is that it only has a gig of ram and will need upgrading immediately. It's been a while since I've done this and prices have gone down a lot. With prices so low, I'm seeing the high performance ram within my price range, but I'm wondering what the difference is between high performance and regular. Right now I'm looking at Omni ram. They have the Optival and Hyperperformance, but I can't really understand what difference it will make to my computer. It won't run any faster, right? But there must be a reason that one is priced $15 above the other. What is it?? thanks!
