If you can afford it, it's probably the best way to go.
As Dvader explained, there are different grades of NVidia graphics cards, the numbers actually mean something individually, not as a whole number.
A lot f people seem to think that the whole number is how you tell how good it is, they think the higher the number the more powerful the card, and they're very wrong.
The first number is the series of the card, the higher the number, the later the series. The last two numbers are the rating of the card.
x10 is basically the lowest possible rating, it's only good for very light graphics usage, such as browsing the internet.
x20/x30 are minor step up form the x10 but still only really any good for browsing, office, desktop games and such
x50 is your middle ground card, it's good for all the above and very low end gaming
x60 is your low end gaming card, slightly better than the x50 and a little more optimized for gaming
x70 is your mid range gaming card
x80 is your high end gaming card
Most people think that for example a 730 will be a better card than a 680, this isn't quite the case, in features it may be a little better because it is a newer series, but in actual power a 680 beats the hell out of a 730 hands down, that's because the 730 architecture is designed for general pc use, where as the 680 architecture is designed for (at the time of release) high end gaming.
There are exceptions of course, when the gap between the series is large enough then it will go the other way obviously, and also when there is a sudden huge leap in tech between two consecutive series (for example when the cards started using DX11 instead of DX10 and so on) then there will be less of an overlap.
It's actually a lot more involved choosing a graphics card than many people think.
Here's a cpmparison chart for NVidia cards, not how anything below x50 isn't even listed? Also note how the 750 is half the performance of the 680.
i7, NV960 4GB, 16GB memory, 2x 4TB Hybrid, Win10.
i5 , AMD 6770 1GB, 8GB memory, 512GB Generic SATAIII + 2TB Seagate Baracuda SATAIII, Win7.
i3, Radeon integrated graphics, 4GB memory, 512gB Generic SATAII, Win8.1.
Q6600, Intel integrated graphics, 2GB memory, 180GB Generic SATAII, WinXP.
