First of all, can I really be called an idiot for saying definite yes? It is only logical to see that for what we know so far about those GPUs they will be much faster then GTX 285. If that so, then we can already suspect (more or less with some accuracy) that it will be faster/much faster then that. So upgrade is viable for some, and for others even more: Folding@Home will greatly improve as well. You can get 5870 for £300+, and so you can GTX 285 (if you can find one, which is only logical if Nvidia is about to release new gen graphics). At the other hand we have dual GPU 5970 which you can get for £500+. Logicaly we can assume, that new Nvidia cards will not be more expensive then that or no one would buy them. In fact they have to be quite much cheaper as even GTX 480 is a single GPU solution. Now, Nvidia was always more expensive then ATI by some margin, and based on those facts I could presume we could expect price mark between £380 to £420 on GTX 480 and £320 to £360 on GTX 470 (as was the case of price differences between GTX 280 and GTX 275 on the beginning). For the case of ATI slashing down their prices, they never do that and they won't do that now. Prices may go down by maybe £20, if we are lucky, but that's it. Concluding, if the performance of new Nvidias will be as good as they say (or anywhere near that) I would say that if prices would be around what I wrote, it will be good value anyway.
