Earlier in another thread, I made a silly mistake by counting app benchmarks (from AT bench) which had a higher score as a win (those benches were lower is better) for BD. BD is consistently better than its predecessor in non-game apps.

Except for BF3, most or all of the new multithreaded games like Witcher2, Crysis warhead, Dragon Age benches favour Intel SB. Even 2 core SBs do very well.
Actually the 2100 is great for games even those new ones which you mentioned which are multithreaded for many cores. Check out AT bench for 2100 vs BD the results may be shocking. I don't know if the AT bench use a 280 or something similar for the gaming benches to highlight cpu differences but still..An i3 2100 is a great CPU for things that don't use more than 2 cores. However, most all new games these days make full use of 4 and even 6 cores (BF3, Witcher 2, Crysis 2, etc). The other thing the Phenom II has going for it is over clocking. They are unlocked and easily hit 4GHz (well, current chips do).
However, with an i3 box, you can always upgrade later to a quad like the 2500k/2600k and then blow the doors off a Phenom II. Same goes for the low end Pentium. Get it now, upgrade it later.
