Upgrading to the 9800GTX

[pwn247]

I've decided to upgrade my extremely outdated 7300GT to a spankin' new 9800GTX video card in my Mac Pro (1,1).

NOW BEFORE YOU SAY IT, I know it won't work right in OS X without drivers; so there's no need to have to explain that. I only plan to use this in Winblows for some Team Fortress 2 and Flight Simulator X.

Here's the video card: 9800GTX: http://www.newegg.com/Product/Product.aspx?Item=N82E16814143137

And what about power? I know there's that nifty power connector for video cards right on the mobo in the Mac Pro (one 6-pin), and the 9800 requires two 6-pin power connections, so here's my question: would this http://www.newegg.com/Product/Product.aspx?Item=N82E16812198016 suffice in allowing me to split the one 6-pin connection on the motherboard to two connections, rendering the card fully powered?

Big thanks, -Eddie

The reason it needs 2 connections is because it requires the power from both connectors. If you could run it with just a splitter, why bother making it with 2?

Also it may run with one or a splitter, but in high loads, the video will stutter and lag.

As with the card, I thought that the compatibility was entirely hardware not OS X not allowing it (I could be wrong of course considering I have never owned a Mac Pro), which brings me the question: Do you plan to swap out cards everytime you boot into the alternate OS? If you do have you considered the wear and tear on the connectors?
