[ut3] Linux Server and AMD Athlon 2600 dual processor

[Kris Kersey (Augustus)]

I agree.  I know that you need to support the lowest common denominator 
but those of us with higher-end chips would hate to lose performance. 
Would it be a big inconvenience to have at least two binaries?  I know you 
have to draw the line somewhere.  Although, one for sse, sse2, sse3, and 
sse4 doesn't sound like a bad idea. ;-)  I'd be happy to do the 
benchmarking to test how much it actually makes a difference.

Thanks,
