I did a quick search specific to this topic. Pardon me if I overlooked an existing thread. I've had a G5 dual 2.0 tricked to the max since it was first released (2003/4). I am using a dual monitor setup (Dell 2407wfp and 2007wfp). Both monitors look great and work well. I am gearing up to finally replace the old system in the next few months and am caught in a quandary. On a regular basis for the past 7 or so years, I've continually upgraded hard drive capacity and memory as my needs have expanded. I've had 2 hard drives fail on me. I replaced the stock video card a couple of years after purchase with the best available for this machine at the time. I used to edit video (rarely anymore). At one point I used a $4k external raid hooked up via an ul4d dual scsi card. The scsci card and Huge Systems raid are still hooked up and working fine, although I don't even want to know how much that 4k paperweight is worth now! Currently, I do quite a bit of photoshop/illustrator/lightroom etc. work. I don't foresee the need for any extensive video editing in the future. My quandary? Limited budget (in the neighborhood of 2-2.5k) v. the ease of future upgrades. I've seen that the 2011 iMac 27" is difficult for the DIY upgrade and currently (according to OWC) there is not an easy solution to the temperature/fan problem when replacing the main hd. The other factor is of course size... If I don't need it, why have that big piece of aluminum sticking out from under my desk anymore? I can see that as SSD prices continue to fall, I will want to eventually have an SSD only machine. Super easy to upgrade a Mac Pro. Not easy with an iMac. The iMac does have thunderbolt and so that opens up truly fast external storage capabilities in the near future (albeit with a hefty pricetag). Likewise, I'm sure the next generation Mac Pros will be equipped with thunderbolt. So, I've been wrestling with the idea of a refurbished (or even ebayed) 2010 mac pro 2.8 quad or 2.26 8 core v. a new or refurbished 2011 27" i7 iMac. I'm sure that the 2010 Mac Pro prices will dip a little bit once the new ones hit in the next couple of months. Thoughts?
