Do you see that small little piece of board with copper at the back behind the AGP contacts? Its above the letters Fo of GeForce4. That little piece of board with copper contacts is going to hit the plastic on the AGP Pro connector.

That 'little piece of board with copper' is the 28 volt power stub required for ADC video connectors. That's required to power the monitor.

That tab is not part of the AGP standard, it's an Apple addition [hack].

It is, however, in the location of the other pins used for the 'Pro' extension to AGP [as shown here]

The card you showed isn't available for the G5 though. It is an AGP 4x card with the Apple ADC power stub.
If the new systems support AGP 8x PRO and ADC as the G5 spec site indicates, they must have moved the ADC power stub.

Unfortunately I didn't get a chance to look inside a G5 well. I should have asked to have it opened. :-(

As far as performance is concerned, Macs and PCs have been stomping on Unix workstations for a while.. at least in raw CPU power. The only advantage that workstations had were 64bit integer resolution and larger memory addresses.


SGI hasn't come up with a truely revised MIPS based machine in ages...they just wait till the fabrication process shrinks and they rename the new processor, making it look like they actually got an updated architecture.
Sun's UltraSPARC is actually quite a bit less powerful than Fujitsu's SPARC64 clone processor and that isn't really impressive either by todays standards.
Personally, if I didn't need huge memory or 64bit integer math, I'd pick a P4, Athlon, or even a dual G4 over any single processor Unix workstation. Even the previous bandwidth advantages of workstations have pretty much disappeared (unless you are using a many cpus).

Now, if I needed 8 processors, max uptime, and tons of bandwidth... I wouldn't buy a PC... but that's another story.

The original question was about the gf4ti card, and the one shipped in Macs is identical to the picture. The tab is in the way of the plastic. Wanna bet $5?
