Hi All, Apologies if this question might be raised in many forums. I use my iMac mainly for editing pictures using photoshop. While my current 2,93 Ghz i7 is extremely fast with all the touch ups, some large pics take a few secs to a min to edit. I was wondering if buying a SSD and connecting using firewire port would reduce the speed drastically. If so what size would be sufficient ? I rarely boot my computer and I dont really care about boot time. I just need some applications like photoshop and garageband to run faster.
