How does this series compare to the NVidia 8800GT?

I want to replace the aging 8800GT in my 2006 Mac Pro 1.1. Is this card substantially quicker, especially in Windows?

    According to Tom's Hardware (google: Graphics Card Hierarchy Chart), the 5770 is six tiers above the 8800GT. The recommended minimum upgrade is 3 tiers to see a worthwhile improvement. So this should be a good upgrade.
