What is the price for the second HD4870?
Why do you think you need to upgrade to an fire rig or an HD5870?
Can you wait for launch prices to come down in a bit few weeks?
I definitely wouldn't be buying a second HD4870 for Xfire right now, especially ince there will likely be a glut of them on eBay once all the new HD5870 buyers sell their old cards.
To which end you can also think of financing an HD5870 purchase by selling your old HD4870 on eBay if price is a concern.
Overall HD5870 > HD4870 in Xfire, maybe not always in performance, but less headaches with no Xfire to worry about, more features, and less power consumption.

Well the HD5870 will have several advantages over 2 HD4870s. It will be a bit more powerful, nicely power efficient and have DX11. However if you've already got an HD4870 the $200-250 price difference is simply enormous. It's your money but for me I'd pick up another HD4870
Oh by the way if I buy me a 5870 will it be bottlenecked by my 720 X3 I got it at 3.6ghz. with 6gb 1066 ddr2. I can always give the card to my wife since she has a 1950pro. I really want a 5870 since they say its around 300$ then I can crossfire another 5870 when the prices come down. Are there any facts that a single 5870 will beat 2 4870s?

You won't have to crossfire 5870's for the coming couple of years, those things will eat Crysis for breakfast, but it may be bottlenecked by your X3 in RTS games (much less in shooters.)
I agree with jyjjy that purely performance wise one 5870 is better than two 4870's.
The 5870 will likely be closer to $400 than to $300.

There's more CPU overhead for Crossfire than for a single card, so your bottleneck is likely bigger on an Xfire setup.
No facts, but early leaked benchies show the HD5870 usually besting an HD4870X2, GTX295, and two HD4890 in Xfire overall at the higher settings.
BTW you still haven't said why you need one or the Xfire, so what is it, other than an ego boost?
When I bought the 4870 I wanted to max out every game there was. Then raised all the graphics on my settings as well. Almost all games looked fantastic with the exception of crysis. I guess I just wanted more. so being a 5870 dx11 I wanted to give the 4870 to my wife and get me the 5870.
