I haven't had an NVidia graphics card since 2002, I've always gone with Radeon, but change, they say, is as good as a rest and I have an NVidia 3D Vision ready monitor so I think I'll make the switch.
I don't really know much about them though. I can get and EVGA GTX 770 SC ACX 4GB w/ steam codes for AC4, Splinter Cell: BL and AO for CHF449 (which is approximately the same in USD), or go for the 2GB card for CHF399. Alternatively I can wait another month and go for the 780 3GB @ CHF620.
These are Swiss prices, so, for comparison I could get a Sapphire HD 7970 Vapor-X 3GB for CHF434. Is the EVGA value for money, should I wait, I don't know if there is a new gen to be announced soon and if prices may fall in the New Year?
