cgminer wont work with nvidia card.....
It does but you will get only something like 60Mh/s or less, totally worthless.
Regardless, I know once he sees it going and understands BTC a bit more, he'll want to invest in a better gpu.
As if his email box isn't overkill enough, I'm going to recommend a 7850 and set it in solo mode for a while and hope his beginners luck pays off once more. ahha

You;re going to Solomine bitcoins with a single 7850?
You crazy..... Might as well do PPS and get something out of it....
Crazy ? Don't mind if I dooo !
Or do you mean "I just bought an Asus ST990fx" crazy ? 
If the days of gpu mining are numbered as some say they are, then one found block is all that is needed to cover the initial $550 cost of the build. The resale value of a 7850, or better, htpc would easily cover the cost of the gpu.
I'm running my 7870, 70-80% pool, 20-30% solo...
