I'm considering buying two amd GPUs for crossfire or two nvidia GPUs for sli with an AMD Athlon II X4 760K overclocked CPU would this be better than an i5 cpu and a single nvidia gtx 760 gpu.

bare in mind the budget should be around the same price and this build will never be upgraded so no need to make any upgrade options as this will be used for the next 4 years in which ill probably re-build another pc with the future parts.
This will be primarily for gaming.

Most of the time single GPU is way more efficient and produce less heat (requires less fan too) than dual GPU set up.
and I've always been an intel fan so I'm going to say i5 with 760.

AMD doesn't make a CPU that can compete with the new top i5s.

Clock for clock AMD is half the speed of Intel.

The only time they come close in benchmarks is when you compare a 8 core AMD against a 4 core Intel, of the same clock speed.

So it would be equal when using all 8 cores, but not too many programs use 8 cores yet, especially games.

I5 > X4 as a CPU unit, crossfire/SLI performance depends on the cards you are gonna use, but generally is more power hungry so leads to need of better PSU. The other thing is that multi gpu solution doesn't scale 2:1 and is also dependend of the game codding, so if you are going to play just random titles i bet single card solution will be more predictable within performance.
