The 3870 performs roughly on par with today's 4670—honestly, thanks to the memes, maybe even better.
If you run dual 3870s in CrossFire, you'll see a performance bump. Theoretically, you're looking at double the power, though in practice, it rarely hits that mark.
In reality, running two 3870s or a CrossFire setup puts you right around the level of a single 4850.

Regarding CrossFire... you can definitely add another 3870, provided your motherboard actually supports it. Which board are you using?
Budget-wise... a 3870 will run you about $233 or more. I’d definitely suggest picking up an identical 3870 to match.

Just my two cents... if you can snag a used 3870 at a great price, and your board supports CrossFire, and your PSU can handle the load, then go for it.
Otherwise... just sell the 3870 and grab a 4850, which starts at around $367.
