I'm personally holding off until 8GB comes down a smidge in price (although it's not super expensive or anything anyway). But until then I haven't needed more than 4GB of ram for what I'm doing
I have found the extra ram is great for virtual machines. Otherwise it's hard to use up even 4. I have 8 and I can give XP 2 gigs in parallels, which leaves plenty for for OSX.
Agreed. I'm majoring in GFX Design and running Photoshop and FF cranks all the way up to 3.2GB used, so I just ordered 8GB G.Skill.web dev and graphic design is not an every day user.... get as much RAM as you can afford.
marc11 and derango, where did you get those prices for the 8GB RAM? Thanks.
Best bet is to open your activity monitor / istat widget and look at your memory usage.
I got it on sale for $65 shipped so I couldn't pass it up but really don't think it makes a difference for MY usage which is typically web browsing and using light apps. I do play some World of Warcraft sometimes and I'm up to a level 26.
I'm pretty set on 8Gb for photoshop, but that's mostly because I'm dealing with rather, uh, large files. When your base image is a 4x5 scan, at ~70MP 16bit color, and you duplicate it several times to create adjustment masks and old-school film-based HDR, you get 3-4gig files pretty quick. 4Gb of memory, and they crawl. 8Gb, and a fast SSD, and they feel like 8MP camera raw files. (I LOVE my new MPB, btw...)
