Two graphics cards better than one?

So I'm theorizing parts for a new build this summer and when it comes to the graphics card I'm wondering if it's best to buy one high end card, or two cheaper ones to run in SLI. In the past I've just used one card but am curious if SLI might be better, what are the pros/cons?

The primary purpose if this machine will be gaming, and I'm thinking about spending $400-500 on graphics. I don't necessarily need suggestions for specific cards but am more interested in the theory behind which would be better, one or two.

It depends on what games you want to play, and at what resolutions. Also remember, spending $400-$500 on graphics for SLI/Crossfire means spending more money on a better PSU, and possibly motherboard, at least another $50-$100 onto the budget.

The strongest single card right now (in your budget) is the GTX 980 for just over $500, that can run 60 FPS in most games at 1440p. The closest thing to that (in your budget) would be Crossfire R9 290Xs (about the same price). But a 980 doesn't need a 850-1000w PSU like those will. If you're just doing 1080p 60Hz it's tough to beat the value of a single GTX 970.

It depends on specific cards. To a point, two cards in SLI/Xfire will outperform cards a tier or two above them. However, I do not recommend using midrange cards to do so.
An example is using two 970s as opposed to a 980 (They used to be similarly priced).

Overall, a single, more powerful card is usually the better option, as you can always add in a second card later.

+1 single powerful card. SLI/Crossfire should only be considered if you already have a really good card and want your system to perform better. If you're doing a straight-up fresh build then only do a single-powerful card.
