Sandy Bridge imacs should be faster - similar to MBPs
GeekBench 2 benchmarks http://www.primatelabs.ca/blog/2011/02/macbookpro-benchmarks-early-2011/ of the new MBPs with Sandy Bridge would indicate otherwise. This review said: "....the fastest MacBook Pro is 80% faster than the fastest previous-generation MacBook Pro.". My guess is a similar situation might be true for the iMac and it will be faster ( otherwise, there's little point to a rev )
When the new version comes out, the iMac you bought won't be any slower..
