Hey guys Recently purchased an i5 15" Macbook Pro and must say am loving it to date. However i held back from upgrading ram/hard drive online when purchasing as i heard its much cheaper to do it yourself. The main area of interest is swapping the 320gb 5400rpm hd for an ssd (approx 120-160gb in size). However recently i have heard of a hybrid hd. I am curious to know what sorts of performance differences i will experience if i take the plunge and also find out more about these hybrid drives. The other area was upgrading RAM to 8gb. What sort of performance increase would i notice with this? was considering this as am told it will enhance the life of my mac. What i do on my mac: word processing, video, web browsing, editing, games Any help/insight would be greatly appreciated Merry xmas!
