I am trying to factor the substantial impact of installing a SSD. I plan on using this computer for the next 2.5 with no plans of upgrading. I mostly use PS and Lightroom where my RAW files are approx. 25mb. As of now my MBP is way under power as CS4 is sluggish. Since CS5 is around the corner and the new features would take advantage of the mulitcore but how much of an improvement would there be when comparing SSD performance? With my fixed budget I would like the best bang for my money. Which would you suggest? an iMac 24 (2.8 or 3.06 mhz C2D + 128SSD HD) or iMac 27 i5? The price difference of older iMac 24 would allow me to get a SSD which I don't mind. I just wonder if the i5 would perform better than the CD2. thx for your help.
