The pure64 port actually is to be considered BETA. We have compiled
roundabout 93% of all packages in sid up to now, but a lot of packages was
not tested to be running at all so far. 

Some people already use it as their desktop system natively; other
people run pure64 chroots on a 32bit host.

32bit OpenGL games do NOT worki with the pure64 approach. You can actually play 
vegastrike or tuxracer, that's what I have tested so far. Tuxracer has
distorted sound on my emu10k1 with alsa, though. xmms works fine.
There is a 64bit version of Unreal Tournament 2004, too.

NVidia drives for amd64 work with kernel 2.6.5. I was not able so far to
get them running with 2.6.6-vanilla or the -mm respective -bk patches. I
did not try 2.6.7-rc1 so far. 

On X11 startup with nvidia drivers set up, 2.6.6+ kernels either hang, or 
reboot instantaneously when appending noapic nolapic to the kernel command line.
