HP/Compaq :: Dv2: Athlon Neo Single Core Versus Turion Neo X2

I was wondering if the new Neo X2 chips in the dv2z are a big improvement over the original Athlon Neo MV-40 single core. IIRC All three are clocked at 1.6 ghz and the single core and dual core Athlon Neo have the same amount of cache (512k) but the Turion has 1mb. I'm up in canada and am considering getting a dv2 to play some older games on, and the dual cores are not yet availible up here, so I am wondering if its going to be worth waiting for the dual cores to become availible up here or should I just go ahead and get one with an MV-40. I already know I am going to be getting one with the HD3410 graphics (not even going to try to game on the X1250, although its probably better than just about everything Intels got out there...).
