Need Insight on HD 5970 x2

Need Insight on HD 5970 x2
Hi guys, new here. I have been following HR for almost a year and finally got the courage to build a PC myself.

I gathered a list of parts needed and right before hitting the check out button, a HD 5970 was 300 shipped on Newegg! I quickly grabbed one and thought that I got a good deal. This week, a local is selling another 5970 for 250$ and I am about to pick it up too. I told the guy leave me a few days to cool down and now here I am asking you guys.

Is it still worth building a PC with 2 5907 these days? News is that the 7xxxx series is coming out soon next year and these 5xxxx cards might not be worth much after. I guess I could always upgrade the video cards later but I just want to know if I build my PC doing crossfire 5970, would it be worth the while?

Thanks,

Stay far away from two 5970 in Crossfire. Reason being that a 5970 is already a dual-GPU card, so two cards would result in 4 GPUs. Performance scaling and (lack of) compatibility with games beyond two GPUs is quite bad, making it not worth it to go with four GPUs like you would with two 5970 in Crossfire.

Not to mention the horrible power consumption, heat and noise of that...Stick to the 5970 for now. If you want more performance, wait for the 79xx series.

by scaling bad, do you mean the performance would increase only slightly vs $, or makes the game stutter or not working well?

Performance would either not increase at all, decrease or only increase slightly, no where as much as you'd expect.

Not appealing at all ! I guess I'll stick with the one I have now.

I read that although 5970 provides better fps over gtx 580, the nvidia card provides a better experience in terms of visuals and consistent frame rate. Is that what you mean by not scaling properly?

The nvidia card providing "a better experience in terms of visuals" is a bunch of crap, but it does offer more consistent frame rate due to being a single GPU card vs a dual-GPU card for the 5970.

Any single GPU solution will offer more consistent frame rates compared to a dual-GPU solution (whether it's on one or on two cards), due to the one GPU solution always offering optimal performance, while the dual-GPU solution is a lot more dependent on drivers, profiles and the game support for dual-GPU.
