2. ATI dont have a 1Tflop chip. They have a theoretical 1 tflop chip. effective it will be alot less.

Also 280GTX got 240 SPs, 4870 got 160 before you apply marketing.
HD 4870 does not have 160SPs. It has 800, just like R600 has 320. They are just different than nVidia's; for one they are clocked much lower.

If HD 3870 has 64SPs, then why do those 64SPs @ 775MHz outperform the 9600GT's 64SPs @ 1.625GHz by a huge margin?

Anyway, people are worrying way too much about 3D Mark 06. 3D Mark 06 is useless, haven't we learned that from G80 vs R600? IMO nobody should be benching cards on '06 anymore; it is 99% CPU dependent on just my 8800GTS 512MB, much less a RV770 / GT200 card.

Vantage is what matters, and of course games matter much more as well. In Vantage Extreme, HD 4850 scores ~2600 IIRC, meanwhile GTX 260 scores 3750~, so the GTX 260 is maybe 45% faster than the 4850. And that is at over twice the price. HD 4850 CF outperforms GTX 280 by ~100 points or so in Extreme as well. Given that HD 4870 should be ~30% faster than the 4850 that would put the GTX 260 only ~10% ahead of it in Vantage. Even GTX 280 would only be ~45-50% faster than it. That means that HD 4870 X2 will blow the 280 away.
