Losing red doesn’t necessarily mean your card has gone bad, how have you arrived at that conclusion? A graphics card sends out a series of signals on a multi cable. Any one of the pins or connectors could be bent. Might be your monitor. If a card fails, it is usually completely gone.
Before you invest in new anything, you’ve got to know what’s wrong. Hook up another monitor and plug your monitor into another Mac. Try a new cable between the monitor and the card.
FCP doesn’t use the card directly for anything so you gain nothing from an improved GPU.
If you plan to use Motion, be sure you buy a minimum card from the specs for that product. Be aware that some cards are specific to some machines. If you don’t need Motion, you can put in a PCI card for $25 but if you need a new AGP card, you spend whatever you can afford and choose the mfr you like.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”
