Which one of these is yours? http://www.dell.com/us/business/p/optiplex-380/pd

Edit: I guess the above doesn't really matter. You are going to be limited to a single slot card anyway due to the BTX motherboard and its layout in the mini tower case. And the SFF suffers from the same issue, plus it needs to be low profile. The GT 730 64 bit DDR5 will be the best card that will fit and work with the stock PSU.
