So I just purchased a quad core 2.66 with 3 gigs of rams off eBay for $549 free shipping. It's definitely better than the 2006 dual dual core 3.0 I had with 4 gigs of ram. However it does feel sluggish at times. I have performed the firmware upgrade in hopes of a W3690 one day. My bucket list: EVO SSD Apricorn Sata III controller 16 Gigs of Ram 1333 W3690 How would my MP perform if I just did the SSD without upgrading the ram? Do these two upgrades really need to go hand in hand? I do real estate photography and some video. I mainly use LR 5.6 and PS CC simultaneously.
