Judging from the recent imac update (I know that the imacs are not montevina but they are similar in spec because of the front side bus is upped to 1066mhz and RAM is upped to the 800mhz both at 2.8Ghz) and seeing all the geekbenches it bests the previous gen iMac (with 800mhz frontside bus with 667mhz RAM) by only about 150 points and maybe 200 at best.
If anything the montevina mbp's higher clock speed at 2.8 and possibly 3.0 will only help improve in speed (I'm guessing the 2.6ghz will become the lower end with crippled cache again).
I guess the only advatage of the montevina would be wimax, GPU (which maybe the only significant improvement in gaming/3d modeling).
But I think nehalem is the one to really look foward to, to see a significant upgrade.
