It seems that the xBench results for the new 21.5 iMac (base model) are about the same - and maybe a tad bit lower - than my late 2006 20" 2.16 Ghz iMac (score: 140.8) My Geekbench score is lower - c.2900 - it seems, but not by as much as I thought. Can this be? Is my machine just as fast as the new base models? I've always found that my 2.16 was a bit pokey, sometimes take 15 secs to launch Entourage or Word and 5-10 secs to launch Safari. Opening documents takes a while as well. I was thinking of upgrading, but these speeds are not encouraging. Any thoughts?
