For all the game benchmarks, first set of results are with AA/AF disabled, followed by 4xAA/4xAF.
Doom 3: (OpenGL) - Map: Demo1
No AA/AF

As I stated, this game is not only intense, you can actually hear the fan on the RX600 whine to maintain a cool core. Unfortunately, when you compare the RX600 to the N5900, it doesn't hold up. Once you turn on AA/AF, the difference is even more apparent.
4xAA/4xAF

The RX600 Pro-Guru barely outperforms its AGP counterpart when rendering Doom3, this is somewhat disappointing, and maybe a possible show of what's to come (or not to come) from this card in future games.
Half Life 2: (DirectX 9)
No AA/AF

Heavy DirectX support for this card should send the advantage the way of the ABIT RX600 Pro-Guru, this however is not the case. The N5900 Extreme handles HL2 smoothly while giving higher FPS results.
4xAA/4xAF

ABIT struggles to give high rates across the spectrum in HL2. It at least outperforms the 9600XT in this space.
Unreal Tournament 2004: (DirectX ) - as-convoy
No AA/AF

All three cards handle UT2K4 very well without AA/AF, and on as-convoy, only the N5900 Extreme claims greater than 60 FPS at 1280x1024.
4xAA/4xAF

When playing as-convoy, the RX600 outperforms, almost giving the same frame rate across the different resolutions. Not displayed above, we did notice that the 9600XT outperformed the RX600 Pro in dm-rankin.
Far Cry: (DirectX) - Fort Demo
No AA/AF

All of the cards took a heavy hit from Far Cry, not even @ 800x600 did I get frame rates that reaches 60 FPS. Even with this, this is finally where the RX600 Pro-Guru shines. Outperforming the other cards with AA/AF turned off.
4xAA/4xAF

Once you apply AA/AF that advantage goes away, however, the RX600 manages to maintain its performance advantage over the 9600XT in this particular game.
