Benchmarks needed

Hi people,

I'm currently stuck with an old 1GB Radeon 4870 (since my main card died) and I'm wondering what games I'll be able to max on it. I've checked all the usual suspects (Tom's, Anandtech, Tweaktown, Tech Review, Tech Spot, Tech Powerup, Bit-Tech, probably others I've forgotten) but haven't been able to find benchmarks for these:

Bastion
Dead Rising 2
Dead Island
007 Blood Stone
The Saboteur
Operation Flashpoint: Dragon Rising
Postal 3
Dark Sector
Spec Ops: The Line
Damnation

If anyone recalls seeing any of these benchmarked somewhere, I'd really appreciate a link. It's fine if the 4870 isn't benchmarked if there's an equivalent GPU there (5770, 6770, 7750, GTX260, GTX550 Ti, GTX650 etc) or even just any GPU in the same kind of performance league.
 
For anyone else stuck with old/low-end hardware and wondering what they can max, I've maxed these on it at 1080p and 4x MSAA:

Borderlands 2 (except depth of field and ambient occlusion)
Black Ops 2 (though many crashes to desktop during cutscenes)
Dishonoured (except huge lag immediately after loading a save then turning around)
Wolfenstein

And through research I've found these should also max fine:

Alone in the Dark (easily)
Prototype (easily)
Medal of Honour
Far Cry 2
Singularity
Red Faction (borderline)
Bad Company 2 (borderline)

But Cryostasis not a chance!
