If the 7850 has 1280SPs and is clocked at 900mhz it should beat the 6950 if the 7700 vs 5770 is anything to go by. So I expect the 7870 to be faster than the 6970 and have all the GCN advantages too. so if it comes out at 299. It will be good value.

If everything I said above is true.

HD6970/50 is Cayman architecture with dual graphics engines in the front end and double the Tessellation Units than Evergreen (HD5800) and Redwood (5700).

Don't expect the same scaling in DX-11 tess games that HD7770 has over the 5770/6770.

Im expecting that HD7870 will be close to HD6950 not 6970, in general.

I wasn't refering to DX11-tess games. I was talking about overall performance. In DX11 tess games the 7770 is much much faster than the 6770.

its because the 6770 is renamed card, its basically HD 5770 with different sticker.

so i agree with Atenra, the gap will be smaller.

What I'm really interested in is the 7990.

Two 7990's with an i7 3820 would be awesome.

You can space the 7990's out with a slot in between for better cooling making it much better for an uber eyefinity setup then three or four 7970's.

Plus you don't need anything bigger then a mid tower case for this.

Yes, I know that. The 7770 is is about 25% faster. with 640SPs and a 150mhz clock speed advantage. The 7850 is going to have 1280SPs with a 100mhz clock speed advantage and the 6950 does have more powerful shaders so yes, the gap will be smaller, but i think it will still be faster overall.
