It would be better to have an 4870X2 and be done with it.

I found I could run many apps at a higher setting without loss of FPS not always more FPS with CF, but I run 16x all the way.

okay, well actually a 4870x2 would cost ~$500. I got both of these 4870s new in the forsale OCN forum for $310 shipped

Also, would you guys think that a 600watt psu is enough for 4870s xfire or do I have to upgrade again......arrrggghhhhh..

Just keep the 4870's in CF... as future-proofing things.

From AMD's website concerning the 4870's minimum PSU requirements:

"500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)"

No reason why it shouldn't handle it.
