Advice on some upgrades, motherboard and cpu

[Stecam]

Hi All,

Currently i have an old i7 2600, and a p8p67 motherboard. As most things with computers i have recently upgraded to a GTX780 (phantom GLH edition) from a 6870, and now the 780 is basically obsolete. So, im heading towards a mobo and cpu upgrade. im looking at a i5 4690 or 4670, and here is where it becomes tricky, what bloody motherboard do i get to try and extract the best out of the GTX780? and possibly SLI because i might get a 4k monitor.

Are the ASUS Maximus worth it?
Z87 v Z97?
Sabertooth?

Too many decisions........... Also, is it worth SLI'ing or should i get a 980 down the track?

Thanks Legends. (also, i dont post here much because i generally find my answer just from reading)

I agree^ The 780 is a good card, but if you plan on upgrading to a 4k monitor, the GTX 980's extra vram will give you better results.
