As far as i'm aware, only the XFX model is actually "slower" and then by only a smidgen. It's still a way better value than the GTX 770, period, by a long shot, IMHO. Some shops are listing the R200 series as having the game bundles, although we won't be certain until Friday when they go on sale. I do agree that they should have the same game bundles as did the 79xx cards.
It is confusing as to why that specific XFX 280X model is slower than the GE - I actually agree that performance progressions should be the norm, not the other way around. It should be noted that most of the 280X models are faster than the 7970GE - the asus DC2T is indeed faster. The MSI gamer 280X is also faster than the 7970GE. Yet, this still does not take away from the fact that other models such as the XFX are clocked lower than the GE, which definitely is confusing - all 280X's should be performance progressions. But, the majority of 280X cards are actually clocked faster and are faster than the 7970GE. The only variable up in the air, with differing rumors, is whether they will have the never settle bundle. Some sites say yes, others say no (I think it should include never settle, obviously).
In any case, the GTX 770 is still a way worse value. Nobody is certain on the gaming bundles just yet since some sellers state that they will have Never Settle (and I would HOPE they have this), and either way you're essentially getting the same performance with the 770 for 100$ more. The situation with the 7970GE is weird. AMD needs to clarify the never settle situation (or perhaps we'll need to wait until Friday) or perhaps the 7970GE is just priced to clear out inventory. I would imagine that it is an EOL product just as the 680 is, and prices are being slashed to clear stock. *shrug*
You do have valid points, AMS. I agree with the points about performance progressions and that the gaming bundles should be held. The situation with the 280X is murky to say the least with some models being slower than the GE and others being faster. This should not be - they should ALL be faster so I have no idea why AMD did that. That said, the 770 is still by far a worse value. Nvidia needs to lower the price to make it an attractive buy. Consider the 770s prior position in the GPU foodchain: the GTX 770 *was* considered the value leader upon launch because it was 50-70$ cheaper than the 7970GE. Nearly everyone, including myself, thought it to be a far better buy than the 7970GE at that time. Now the role is reversed; the prior value proposition of the GTX 770 is gone - I would like to see the value proposition return. If it lowers in price by 50$ or so, voila, that's a done deal. Why would anyone disagree with that? Even a 350$ GTX 770 would be a viable contender. At 400$, it's much harder to recommend, especially considering it's a 2GB card.
