Short answer: Yes – Oliver Salzburg Jul 5 '12 at 15:53
What makes you think you shouldn't? That's what I'm curious about. Is it the fact that the system only has 3gb of Ram that makes you think you shouldn't? – Bon Gart Jul 5 '12 at 15:54
I meant will it run fine and will get the 64 bit performance on 3gb ram or will I need 4gb ram for real 64 bit experience ? – Dagger Jul 5 '12 at 15:58
"64 bit performance" should be about the same as "32 bit performance". – Hennes Jul 5 '12 at 16:03
For most people "64-bit performance" with Windows means being able to install and make use of more that 3 GB of ram at a time. – martineau Jul 5 '12 at 17:08

Yes. All Core 2 Duo CPUs support 64-bit. From Wikipedia:

Intel Core 2 (including Mobile processors since "Merom")

From the Microsoft minimum specs, you'll need at least 2GB, which you have. You might notice a modest performance increase from 64 bit, but it won't be huge.

Of course, the more RAM, the better!
