oh yeah, one more thing...
We need the Ati Radeon 8500 as a BTO and we need it now!!!!
infact screw Nvidia entirely and just go for either a Radeon 8500 or GeForce4 Ti in the towers, Nvidia would still be supplying apple with the ultra high end card with the killer GPU and bags of Video RAM.
In my opinion, largely based on benchmarks I've read on various sites, any G4 Tower with any of the graphics cards they currently ship with can get a framerate so high you're not going to notice if it's 2, 3 or even 4 times faster anyway. A TV is only 25 or 30fps depending on where you live, video games (mainly arcade machines) have been 50 or 60fps for decades and the framerate is perfectly smooth.
An Ati Radeon 8500 has the capability to make 3D look better than any GeForce card because of the Truform technology, I'd rather play with all the eyecandy on and have really smooth looking graphics at 50 or 60 fps than have obvious polygons on the edges of everything and a frame rate in the hundreds I'm never going to notice anyway.
Apple might aswell offer something that can handle reasonable framerates as well as make the onscreen image look as smooth as possible. For example:
We've already got the Ati Radeon 8500 as a BTO option on the Xserve, it wouldn't surprise me if we saw it as either standard issue in place of the Nvidia GeForce4MX or as a BTO option on the G4 towers.
As for the framerates, here's some info from a pretty extreme benchmark on barefeats...
They're framerates from Quake III running on a dual Ghz G4 with maximum settings at 1280 x 1024 and in 32bit colour :
GeForce4 Ti : 123.1 fps
Radeon 8500 : 77.2 fps
I hope we get this card, if anything just so we have a choice over the high end card.
