Considering replacing 4870x2 QuadFire

I've been eyeing those new Sapphire Vapor-X 4890's that just popped up on Newegg:

I was thinking a pair of these overclocked to 1GHz might be a better option for me, especially considering how much more powerful it'd be running games that don't support CrossFire, such as WoW. Thoughts?

WTF are you on about?

K first of all you guys need to read his post more carefully.. Although i do somewhat agree. You are theortically better off just sticking with what you have. 1 4870x2 Card is alot more powerful then a 4890. Now 4870x2 is esseintially 2 4870's combined. And you are right that some games dont go so well with crossfire/sli but most newer games are getting there. Plus if your worried about WoW i got news for you. You are already like killing the game graphics wise with a 4870x2 pair. You wont see that great deal of a preformance if you switched over. Although the 4890 pair looks tempting your gunna be dissapointed when you get rid of your two 4870x2's and find out a month later that all those sweet new games you want run like 40 times better on them then your 4890's. Good luck

Well, you can get a good price i am sure for the two X2's so you probably wouldn't need to spend any extra cash.

Last i checked crossfire on it's own is better than quad fire pound for pound and the two 4890's will be better than one 4870x2.
