Good card, I just found a 560 DirectCU II for £167.99 but the MSI Twin Frozer II 560ti is only £175.99, personalty I would go with the ti.
Nvidia have done the same thing as they did with the 450 and the 550, they have just made another version of an already existing card.
It's not really a bad thing but first we had the Nvidia 550 and AMD 6790 releases which apart from the water cooled version of the 6790 are no better than cards that only cost a few quid more and I feel like this is the same thing all over again. Saying that though there is also the normal DirectCU version of the 560 for only £155 so that is not to bad, still, it would have been nice to see a new card slightly better than the 560ti rather than one slightly less better.
