The Sandy Bridge processors are considerably more powerful than current AMD ones. The extra processing power 'headroom' gives a degree of extra future-proofing over the AMD and may result in systems using the intel's being able to handle future demands (in COD and elsewhere) better than the AMD.
For me, the price difference between an AMD and an i5-2500K is not an issue. The intel is well within budget for my upgrade. The extra performance certainly makes the 2500K the current 'sweet spot'
(I got hauled over the coals for using that term 'future-proofing' in a previous post - but it makes sense to build a system that has as much headroom to deal with future needs as you can afford. )
Also Oldschool 61, we can all see that you have an AMD fixation - but the OP did make clear that he wasn't interested. It's a bit disrespectful to keep harping on and on and on.
For myself - I did consider Bulldozer as an option, so I'm not some Intel fanboy, but as I want the new system to play COD - in 2 weeks 
- and Bulldozer won't be out until June...
