The GTX 760 Ti is def the pick of bunch imho, big upgrade for me coming for 660's.
960 shaders VS 1344 shaders, 192bit bus VS 256bit bus. Pair of them should do until Maxwell / AMD's new cards.
The other cards price VS performance is more shocking the higher you go up from GTX 770 through GTX 780 and finally Titan..
760Ti price. $299 / £197.1 + 20% VAT = £236.52 + Hike = £265.00 in the UK?
£265 would still be reasonable IMO, 760Ti, likely to be around if not higher then 670 perf. On special offers may see them in the £220-240 mark and should compete with the 7950 in most areas.
Tbh all Nvidia really needed to do was drop the new cards into the 6x0 price brackets to win people over. You never know the prices speculated may prove to be wrong, guess we'll find out in a few days.
Also, this isn't a place to discuss who should have what hardware, personal preference is just that.
