I'm not sure if that's such a good assumption. For example, We stick to
32bit at work since some of the special purpose hardware we use don't have
drivers for 64bit.

So, to use KDE 4.10 & qt 4.8.x on el6 32bit, do I need to build all rpms
myself to avoid this atom business? The problem is it affects every qt
based compilation on the machine!

If that's so, I wonder what performance would I be losing if I'm on
something like an i7 or at least a core2.

Thanks,

Syam
