My doom3 benchmark is with 8x AF. My FarCry benchmark is with no AF and is still lower FPS on average. You're gonna need more power for D3D games, thats just how it is.
But still, it should be playable. A 4200 Go isnt top of the line, but theres no reason he should be getting "1fps" in HL2. Half-Life 2 runs a lot better on my machine than Doom 3 did, so yeah, id say its ok to say that if Doom 3 runs Half-Life 2 should too.
