Upgrade from 4890s in XFIRE - Page 2

I doubt XFIRE 4890's are even close in performance with the 6990's; there's a reason why it costs more. The 6870 has performance very close to the 5870. So 6950, 6970 and 6990 is going to be a lot faster than XFIRE 4890. While dual 4890's might have performance slightly better than one 5870 the minimum FPS is still going to give the 5xxx/6xxx series cards a slight advantage. Sure XFIRE 4890 can get higher frames than 5870 but what good is that when its minimum frame is lower?

Most also do not consider the complications and problems that come with XFIRE configurations. Sometimes XFIRE works fantastic and you get great frame rates in games, sometimes they drop out on you for no reason and you're running at half your FPS. Many games still do not support multiple videocards so you'll never see a performance gain. If the OP wants to upgrade to get rid of his XFIRE configuration the 5870/6870 would offer performance close to that of his current configuration. Dual cards are great when they work correctly. Scaling for dual cards is a lot better on 5xxx/6xxx series cards than previous 3xxx/4xxx generation.

Otherwise the OP can get 6950 and unlock it or get a 6970 which is 5870's replacement or get 6990. GTX 570 and 580 can be an option but price maybe an issue if the OP is not willing to pay the price. The GTX 4xx and 5xx series will also give a higher minimum FPS in games.
I was referring to the 6950 as being a side grade not the 6990. Its not worth it for him getting the 6950 and I answered his question saying that that 6990 was the only new dual gpu ATI has to offer at the moment. That card is in an entirely different league and will destroy xfire 4890's because it is in essence x2 6970's. I think even a GTX 570 would still only be a minor upgrade which is why I recommended either a GTX 580 or ATI 6970.

what budget?

P.S. 4890 CF performs +/- <5 FPS to a single 5870 in the games played by the OP and a single 5870 per (winner depends on game and resolution used). And a single 5870 is still actually faster then a 6950 in FPS games and even beats a 6970 in some games (depending if AA is used or not).

so anything below the 6990 or a GTX580 is not a worthy upgrade for me is it????

also just to clarify; is the 6870 faster than the 5870??? (I saw this in the graphics rank listing and was kinda confused)

is a 6950 better than 4890 in CF????

The 6950 or 6970 would be a nice upgrade. Or the 570/580.

The 6870 is a slight bit slower than the 5870, but has a stronger tessellation engine. And yes, I'd say the 6950 would be better than 4890s in Crossfire. 2 4870s are about equal to one 5870. If nothing else, the power consumption and heat would drop tremendously.

4890 xfire = roughly gtx 480. A 5870 would be a definate downgrade, I would recommend upon a 6950 which could be unlocked to a 6970 because you prefer ati.

so, on the whole;

would it be best if i went 6970 (2GB), Asus Rampage 3 Extreme and a CM HAF 932 casing?

PS-or is the R3E not worth the upgrade
