Lenses for my DSLR.

I recently bought a Nikon D90 for $50 off of KSL Classified. My original intent was to flip it but a little after I completely fell in love with it.

Now that I know I want to keep it should I get the 80-200 F2.8 for $250 or the Sigma APO 70-200 F2.8 for $400?

I was mostly curious of how the 80-200 performs on this older camera because it has a screw-drive focus motor.

any suggestions would be appreciated.
