Crazy Chris* Tom of AMDZone has been benchmarking the latest edition of the Quake series on various bits of juicy graphics hardware.[AMDZone]Clearly with AA enabled the balance starts to tip towards SLI especially at higher resolutions as we would expect from the Doom 3 engine. We will continue to add additional graphic card configurations to our benchmarks as time allows as we will add Crossfire results, and other Radeon and GeForce numbers soon. From what we see so far if you want to deathmatch with Quake 4 at high resolution and image quality then you will be spending several hundred dollars on a high end video card if you have not already.
*Chris may not be crazy, but I am an apparent alliteration abuser.
