Do you know if the 256MB on the GPU are really used? I can't decide whether I want the high or low end iMac/MBP.
I would say the extra vram helps when your playing on high settings with everything set to high. I would go with the 256mb vram. You won't see difference in 128 or 256 unless your game play is stressing the video card at times, then the extra 128 comes in handy. It's only a $75 upgrade and you won't be able to upgrade later without voiding your warranty ;/
As for the iMac Intel 2.0Ghz 17" game play its going to be the same, you will have a smaller screen and only 128mb vram but its still going to give the same fps as its the same card (x1600) you can overclock them a little bit, but I would not do that until your warranty ends as the imacs themself run a little hot and you don't want to make them run any hotter. If you have a small fan you can put around your imac to suck some of the heat out then I would give the overclock a go (small overclock, dont go crazy).
I would also look on ebay as you can find a 20" imac intel with the 17" specs for the same price as the 17" maybe a few bucks more not much tho. ebay.com is great for buying brand new (with warranty) apple products. When I buy my second one (if I don't buy a newer upgraded version right when it comes out) I'll be using ebay for sure as they have great deals.
