If you can get one for $75, that's worth it. A 3870x2 is somewhere between a 4850 and a 4870 when CF is supported, IIRC, which is faster than any current $75 card.

does the x2 mean its 2 gpu acting as 1 gpu?

Yes, the 3870x2 is basically 2 3870's crossfired on a single card.
At best, it will perform a little better than a 4850, at worst, quite a bit slower.
While it is not bad for the price, I would recommend a 4850 for just a few $ more.

A 4850 will give you similar performance (much better in titles that do not support CrossFire) and requires much less power.
It will also handle AA much better than an old 3K series card.
If I remember correctly, they had an issue with massively lower performance when AA was enabled.
The new 4k series has fixed this issue and now offers 8xAA with next to no performance hit compared with 4xAA.
