RUNNING DP 4.5 and FCPHD on the same machine

[Dane]

I Run FCPHD with BlackMagic Decklink uncompressed
SD and HD card on on My dual 2Ghz G5.
I am thinking of moving DP 4.5 to this machine from my Dual 1.46Ghz G4....
Is anyone using a similar capture card and FCPHD with DP4 or 4.5 ?
If so how's it working running both your DAW and NLE on the same machine... (not nessarily in unisyn)

I want to use to G4 for DV and SD video only.....

I am adding a G4 PB with Traveler and MachFive V2.0 (when it releases) as another Synth'
