Hey, a friend gave me a free nVidea GT340, and as I only have macs the only available system was my PowerMacG5 so I put it in however when my display is directly put into the graphics card it does not display anything.

I am currently running of my original graphics card with the GT340 in another slot.
The problem I am having is that I am not sure whether or not the graphics card is actually running, it is in my system profiler but it does not extensive information which leads me to think it is not running.

Here are my system specs:
 Machine Name:	Power Mac G5
  Machine Model:	PowerMac11,2
  CPU Type:	PowerPC G5 (1.1)
  Number Of CPUs:	2
  CPU Speed:	2 GHz
  L2 Cache (per CPU):	1 MB
  Memory:	5 GB
And here is what appears for the graphics card:
  Type:	VGA-Compatible Controller
  Bus:	PCI
  Slot:	SLOT-3
  Vendor:	nVIDIA (0x10de)
  Device ID:	0x0ca4
  Revision ID:	0x00a2

I high doubt that, that card will work in your G5..
True, it won't work in any PPC. There's no PPC ROM and driver for this card (to the OP: card for PPC must have PPC ROM on it).
In PCIe G5 you can run only (original Mac or flashed ones):
– GF 6600 series
– GF 7800 series
– Quadro FX4500
– ATI X1900
