but you might know that the V5-5500(dual chip) will be used as a V4(mono chip)...
And only V3 will run in 3D mode under OS 3.x.
Nope. My 4500 runs equally well as my 3000 on my Prometheus using Warp3D. But on 2D 3000 is much faster on some operations, 4500 driver seems to be lacking on hw acceleration, they never developed it to a finished state.
