AuDioFreaK39 :
The new card should be available at some point in September
Meaning their 55nm cards are far off. Obviously they are running into problems if their solution is to unlock some shaders on the still expensive G200 chip than to start selling a significantly cheaper & faster 55nm refresh.
So all the hype/hope of the 55nm by September seems unlikely now, the bigger question is when will it arrive, and can it do anything to challenge the X2, sure doesn't seem like a small boost in shader speed alone is going to be convincing as a later launch, it's more likely to continue the win some / lose some that is the current situation, maybe breaking o creating a tie compared to before.
I'm also skeptical of adding a few shaders to the GTX 260 helping all that much, in the shader department the GTX280 is below the HD4850, so those games that were shader and bandwidth bound will still favour the HD4870, those that are still texture, ROP and VRAM bound will still favour the GTX260/280.
All this essentially does is make any tie or close battle a little bit better for the GTX260+ or whatever it's called, nothing revolutionary.
And for $50 more, would you even bother?
Seriously, this news is as boring as the GF8800GTS-SSC with 112 SPUs, the real news was the G92, and the same situation here, who cares about the 260+, the 55nm refreshes are what really matters, until then it's window dressing on a delay.
