Hi, all, thought I would see if I can get some advice on a new iMac that I'm going to surprise my wife with for her birthday soon. Was originally going to wait for the refresh, but from all the comments here there doesn't see to be a whole lot of difference in what's expected for the refresh so I'm going to go ahead and bite the bullet now. Currently, she has a 2008 model iMac 24" that's been given us some problems trying to run all the apps she tends to have open - Photoshop/Bridge CS5, Lightroom 2, MS Office (mostly Entourage), GarageSale (eBay listing app) and Safari/Firefox with entirely too many tabs open. It's a C2D system with 4GB RAM currently, but she has issues with locking up and general system speed. We've had various issues with that system as a whole, repaired a couple of times for bluetooth and superdrive problems. With all the photo editing she does, I wanted to get her the 27" iMac, and I'll wipe the 24" and give it to the kids or something Anyway, with those apps - would the 3.06/3.33 C2D system be snappy enough or should I spring for the i5/i7 system? I was planning on starting off with 4GB of RAM, but it seems common thought is that those apps need more RAM than processing power. So, my thoughts were around sticking with a C2D system and popping 8GB RAM in there instead of going up to the i5/i7. Seems to be some talk about whether or not a graphics upgrade would help with the Photoshop stuff (going from the stock ATI 4670 in the C2D system to the 4850) so I'm not sure if that's a worthy upgrade. I welcome any and all advice or thoughts on what might be the best route to take, thanks all!
