The trouble is, you might always be *waiting* for the next latest and greatest, I was doing the same and just bit the bullet and got the current best option at the time. There is always going to be something better in the pipeline every 6 months or so. I have had my 27" iMac 'Sandy Bridge' for going on 4 years, I really want the 5K also but can't justify the expense as this one is still doing the job (a bit slowly for my taste). I am lucky in that my Spouse could care less what I buy (has something to do with the $5K in sewing and crafting stuff SHE has)
Happy wife, happy life!
