Just Cause 2
Just Cause 2 is one of the older titles in our suite and uses DX10 visuals. It's no longer cutting edge, but it's still a lot of fun and can be used to cross-reference older reviews.
Just Cause 2 has all the GTX 770 variants lined up perfectly. Zotac's AMP! Edition is the quickest of the bunch, followed by Palit's JetStream and Gigabyte's WindForce 3X. There isn't great deal between them as far as framerates are concerned.
