So at last I want to know that how much is the XE SLI futureproof ?? My own anticipation says maybe 3 - 5 years ?? Whats ur thinking ??
Really depends on which path game/hardware developers choose i guess. It will just be a case of keeping your fingers crossed that your hardware will remain competitive ultimatly.
'If' Kepler destroys Fermi for example, game companies will begin to cater to the newer hardware. Won't be long before your cards become less and less relevant with cheaper, more efficient and more powerful GPU's for game developers to work with.
On the other hand, if the next few generations follow the same trend as the previous two generations (4xx/5xx for Nvidia, 5xxx/6xxx for AMD) then your cards should be equal to a couple of 670's maybe. And equal to a couple of 760's if the same trend continues. In which case you should be okay for at least 2-3 years imo.
And that's not mentioning what direction DX11 will take and how much more intensive it can/will become - especially with better hardware potentially at it's disposal.
Too many unknowns really. But by buying the best you can get now - you'll certainly lessen the risk of being left behind. Certainly be stronger than my soon to be 560 2gb Sli setup - which i also intend to last me for a good 2-3 years!
