On a scale of 1 to 10? I give it a 3 or so.
The nVidia 7 series is quite old now, and even when the 7300 GT came out it was a slow card. Now that's not to say it's a bad card, if you're on a budget and not looking for a gaming video card it will work just fine for a work computer, but if you plan on any sort of gaming I would suggest finding a different card.
A few good options would be the 7600 GS/GT if you're on a really tight budget, though the 9600 GT and 8800 GT are better options if you plan on any sort of heavy gaming.
