Well the 64 bit drivers (AMD-64) Have no optimizations (regarding Gaming
/ 3D Graphics) so they end up being slower than 32bit in tests.
I think the great thing about AMD-64 is that they run so well in 32 bit
mode.
I'm not going to bother with 64-bit drivers because games etc. are not
yet 'proper' 64-bit - so they end up running slower than 32bit again.

Yes.. true. *wonders if DDR2-533 will ever have tight enough timings to be worth it*
lol at DDR2-CL4
