Two graphics cards, good for mining?

I have shuttle server that I acquired from work which I used for some testing. Over my travels I've acquired a couple GPUs. One is an ATI FireGL 3400 the other is a nVidia GeForce 6200. I've put them both in the same box and run bitMinter and guiminer and both say that they can't find any mining hardware. Running server 2003 with 4GB of ram with a Pentium duo E5700.

Any help is greatly appreciated.
 
I highly doubt the 6200 would work. That's way too old.

You are also running 1 Nvidia card and 1 ATI card together, that's a little sketchy. And server 2003 might not be the best choice of OS, you may want to consider Lubuntu, as it uses less resources.

Try just the ATI Card on a Lubuntu install.
Realistically, that hardware isn't going to generate any bitcoins. It's so far behind.

Under devices on the default tab it says "No OpenCL Devices"

So you are suggesting that I run ubuntu on this machine with just the ATI card, no problem I can do that.

I come across servers which are 3-5 years old that customers are retiring, usually dell power edge 2950's etc with some nice processors in them. I don't usually pick them up as they are a pain to lug into my office and will just sit there if I'm not using them. Would you suggest picking those up to run a mining app? What app do you suggest?

Again any help is greatly appreciated, I have access to all sorts of hardware I just need to know what I should get. I'm not worried about power, I can write it off on my taxes as a business expense. I've also though of making some Hyper-Vs on my clients servers to mine...
 
You will get the best results from a PCIe Radeon GPU in the 58XXX series or higher.

Nvidia cards are not nearly as useful, and CPU performance is minimal and negligible. It's all about the powerful GPUs.

The server CPU won't do much, so unless it has multiple PCIe x16 slots, it's not worth the power consumption.

Remember; you need to generate more income than this old tech is going to consume in power.
And Old tech can consume significant amounts of power.

You will make better progress with low power motherboards and CPU's, with high end GPU's. Bitcoins are also significantly harder to mine than they were a few years ago. And it always increases in difficulty, with pools of hundreds of thousands dividing the profit equally. You won't make much on that, except heat and hydro bills.
