hi
Let me start by saying , I love my 24" imac. its the 2nd 3.06 I have had.
I sold my first to buy the i7 quad core. Now thats fast but the screen size was a big issue with me. I sold it in a week. I have had 2 i7 in the last 2 months from mac mall. I thought I jump the gun on the first one, Bought the 24 i have now and another i7. Same thing just to big but amazing mac for the money. sold that one as well. So I know what speed is. real world speed. In imacs anyway. my daughter has the 21.5 3.06 500 gb and my wife has macbook pro 13" unibody 2.26 , i put samsung ssd 256 in that and i know people have been ripping the samsung. But i have both the samsung and intel. I can tell you again real world, its much faster than stock hd. But thats for another day.
but getting back to the mac mini, yes when I first picked it up and plugged it into my 24 cinema display, perfect size for me. With the same display as the 21.5 and 27. I said this is a slug. it had 2gb ram and 320 hd picked it up local for 300.00. I already owned the ram and ssd to upgrade. I upgraded the ram and put ssd in the boot up drive and 500 gb in optibay. I was amazed how it works. not to say at all thats its as fast as the i7's I had but fast. it boots up in under 20 secs. at least 10 to 15 secs faster than my 24". it opens all my programs faster. I thought for sure I would lose out on the video card end of things, but it holds its own and opens photo's that i shot in raw with my nikon d90 as fast or faster than my 24 and opens my apps faster than my 24. all of them. photo shop, ivideo, iphoto to name a few. I don't know how it would do with super big files, video wise or gaming not a gamer. It should be as limited as the card. I don't care what anybody says, the biggest and best bang for your buck in upgrades is SSD drive. It is night and day. you can change all the ram you want, for the average non gamer or graphic designer
you won't know if you had 4gb or 8gb ram in your mac.
I'am going to hold onto this mac mini until mac comes out with a 3.0 plus mini. I hope this year. Then I will upgrade one of those.
I also put the ssd in the optibay of my 24 at first. and used the ssd as boot up. that was really fast. much faster than the stock drive and the upgraded mini. I just really wanted one of the new screens, and I had the 24 running the 2nd 24 display, works great. just want 2 of the same displays.
well that was the most I typed in years.
so I hope you don't think I'am putting down the 24 imac, because I love mine.
just its amazing what you can do with those little mini's. It just floored me.
Why don't you try taking your old one apart and try it. you will come out shaking your head like i have.
For most people real world (not there ego !!!!) that little mac mini with the upgrades is all most of us would ever need. (but i have ego too and like to play)
thanks
