GeForce 7900GTX does not support CUDA and it can't mine anything...

While it is a good card it is not a good card for mining MemoryCoin.
What you could do it turn it towards another scrypt coin and then trade for MMC.
This website will give you an idea of what performance you can expect from the card.

I hope it helps.

Is there any software that will let me test around with this old card?

Thanks!

I can only recommend scrypt mining in order to buy MMC at market price with mined BTC.
