So, I'm looking at the 27" iMac i7 with the ATI 4850 graphics card. The price is still a little too high for my liking, but I'm hoping when new ones get launched (according to the MR Buyer's Guide it's about every 7 months or so) that there's a trickle effect and the i5/i7's are available in the lower-end 27" iMacs. Does anyone run World of Warcraft or other heavy resource games on a Core i7 or i5 iMac? I'm looking for realistic performance. Right now on my old, 8 year old Windows desktop, on low settings, I'm barely breaking 15 fps in a crowded environment. In smaller group or solo play I'm around 30 fps. My iBook G4 (PPC, mid 2005) has been unplayable in group environments since the last expansion pack launched (1 fps, I've even seen it say 0 fps) but if I'm able to log into a solo area I usually can pull around 10-15 fps. That being said, what can I reasonably expect? I priced out and contemplated the idea of building another Windows-based PC but since I bought my iBook I've really enjoyed OSX even over Vista and 7. The biggest thing that concerns me is the fact that you can't upgrade a video card after purchase in an iMac and I'm a little worried about the ATI Radeon HD 4850 just not being STRONG enough to handle the good stuff. I'm hoping that Apple bumps this up to an optional 5000 series card so we can have DX11 support.
