[authorleon]

Hello all,

I have a mac pro, which is as follows:

Model Name:Mac Pro
Model Identifier:MacPro1,1
Processor Nameual-Core Intel Xeon
Processor Speed:2.66 GHz
Number of Processors:2
Total Number of Cores:4
L2 Cache (per Processor):4 MB
Memory:8 GB
Bus Speed:1.33 GHz
Boot ROM Version:MP11.005C.B08
SMC Version (system):1.7f10

I have a 7300GT which is very painful within avid, or fcp. I also have premier.

I have these cards around:

9800GTX (Take 2 x 6 pin power connectors (512mb))
HD5550 (1Gb version)
HD6770 (1Gb version with 5 MINI dv out's)

In the spirit of saving money, I would like to know if I could use any of the above please, Flash the rom or what ever needs to be done.

I am asking here if anyone has any of the card working in their Mac Pro 1.1.

Thank you

I think 9800GTX and 6770 is good bet.

Does the PCIE auxilary power cable that comes with the PC GPU work with the MacPro PCIE Aux port on the motherboard?

The Mac Pros use a proprietary Mini PCIe power connectors on their logic boards. They are like $5-8 a pop on eBay.

Could I just use a molex --> PCIE 6-pin adapter since they're available locally? I assume I'll have a molex power cable dangling where my second optical drive could be...
