To be honest, you won't be terribly disappointed with either choice as long as you know the caveats to each one. Both have upgrade paths (as long as you spend on the AM3+ for the 965) and both are just about evenly priced. Sure, you can spend a bit more and get an 1100T or 2500K, or you can just wait a while, save your money and go for a dozer here in the next few months (after the benchies come out and all).
As for the delays to Dozer...if you know the track history for both Intel and AMD, then you would also know that delays are a fact of life. If they try and rush the product, you end up with mistakes like the one that happened to Intel with the SB mainboard chipsets.
For my own peace of mind, I would much rather see Dozer come out slightly later than expected, but absolutely pristine in every other regard, rather than something rushed out to market and rife with errata.
I am also hoping that AMD does pull off a performance coup, if for no other reason to show that they are still in the game and to keep Intel humble enough to continue making quality product at reasonable prices rather than sit on their laurels and every few months come out with a 200Mhz bump to the same kit for the same price.
