Having retired and no longer using Photoshop, Corel or QuarkExpress, going to 'downsize' from my Quad Core Mac Pro to a new iMac. From users of the current series, is there any noticeable performance difference between the 2.5 and 2.7GHz CPU's? Would imagine not a great deal with some 7% difference in capacity.

Also any noticeable difference in performance between the Radeon 6750 and 6770 gfx cards please?

Thanks.

It's not a good time to be buying right now. The 2012 refresh is imminent.

The best time to buy is when you have the money and new models could be yonks away down under.

Thanks BlueFinch ~ you used both models?

Lol, nothing like buyer's remorse.

I would urge you to wait for the update if you can - I'm sure you will get a lot more for your money if you do. It's *surely* weeks away at most.

That being said, here's a link to benchmarks on barefeats.com, and here's another only including the 2.7 which may give you a little insight as to which model might suit :)
 
Best case, you'll see 7% in cpu bound apps. i.e., handbrake or similar. if you're doing general stuff i suspect you'll see closer to 0% difference in the real world, as most apps are IO or memory bound, not CPU bound.


More important is the video memory, but unless you're gaming there's no point upgrading to 1gb there either.

It depends what you're using the machine for really.
 
I'm sure most apple products ship to us, uk and au around the same time? Best to wait anyway as you will get a better product for your money and not paying this year prices for last year hardware.
 
Wait till refresh

Low end 21.5in and 27in iMacs will be superior to mid level iMacs currently on sale - also, if you go refurbished route, a i7 21in iMac or i5 3.1Ghz iMac at 27in on July 1st will not break the bank.
