Need Advice: Thinkpad T60 or T61?

[Clint Pachl]

I've been using an IBM Thinkpad T22 (P3 900MHz) laptop for quite some 
time and I want to upgrade. I am looking for some expert advice on what 
to upgrade to in the Thinkpad T-Series.

Two main considerations:
1. Core Duo 32-bit (T60) or Core 2 Duo 64-bit (T61)? I've only used 
i386, should I think about amd64?

2. I would like graphics hardware acceleration. I know I need to stay 
away from nVidia. The T60 comes with ATI Radeon and the T61 is the 
integrated Intel 965GM.

Is there anything else I need to be concerned with regarding OpenBSD on 
the T-Series? What would you guys choose and why?

Thanks,

Clint
