Really?  I find that odd.  I didn't notice any drastic change (though I 
didn't do any hard core testing) between 32-bit and 64-bit 4.4 on my 
quad-core boxes running the 9550SX.  However, that could be just me.  
Apparently, I am just a young Skywalker in terms of tuning these 
new-fangled 3Ware cards and dealing with partitions/filesystems/etc.  
Without Josh Baker-LePain's kind advice, I'd probably still be wrasslin' 
with it.  :)
