Reply to Anyone run 2.6.1 on an older Macbook Pro (mid 2007)

I've been struggling to find a computer with the little cash I have lately that will run Traktor without hiccups. I own a cruddy HP g72 that can barely run 2.1.2 with and Audio Kontrol 1 interface. My buddy has an old MBP from 2007 that he never uses with a core 2 duo @ 2.6ghz, 4gb ddr2 667mhz ram and 200gb 7200rpm harddrive. He said he would sell it to me cheap and for one, I feel that OSX just does a better job with background processing and allows little to no CPU spikes. Compared to the computer I have now which spikes all the time. And i know, "check the windows optimization page on NI website". The guide works for the most part, but who wants to strip down their entire computer everytime they want to dj? i just want to hop into the program whenever I want and not have to worry about turning off this and that driver. Anyway, the reason I'm debating is because I'm also looking at the z2 mixer which only works with 2.6. LONG STORY SHORT, would this MBP he has cut it and have a lower CPU load then my current computer?
