Originally I wanted to buy an i7 with SSD and a conventional but got stuck in a time crunch, needed the hardware fast, so I bought an off the shelf unit at a local Apple store with a single conventional 1GB drive that has just packed it in. IIRC its a Samsung HD if that matters any? I managed to get my files backed up so im not at a big loss here however I figure if Im going to open it up I might as well get the best performance out of it. I also would like to install dual drives so Im going to list some questions out and would greatly appreciate some tips on whats the most reliable and top performing hardware upgrades. 1. SSD? 2. Brand and size drive? 3. Single or dual drive? I tend to fill up 500GB of space or so every few months and do manual bu's presently but always liked the idea of an OS drive that doesnt get used for storage and supplementary dries for storage. Ran my towers this way with success but was curious if there are any downsides that have popped up since the dial drive options was added to iMacs? 4. RAM. I have 8GB now. Is it enough or do I need to step up to 16GB? Using photoshop a lot 5. Current OS Snow Leopard. Should I do the Lion upgrade while im at it? Any performance/stability benefits? 6. Go *******s, toss in the towel and use it as a display only and step up to a fresh tower? Thanks much!
