I have a MBP ('10 15in 2.66 i7 w/ 8 gigs of ram) It works great no problem at all. But I feel like I am compelled to upgrade. I have never seen a bump in geekbench scores like this. Almost double for some. I am asking all those who are going to NOT upgrade to convince me why I should not upgrade as well. Apple products are one of the few things in my life that I am always motivated to have the latest and greatest. No rhyme or reason to upgrading other than having the newest toy but this one is just killing me. Okay someone talk me off the ledge.
