Upgrading graphic card

[Icycookies]

Okay so i was planning on upgrading my MSI 660 ti pwr edition this summer had hope maxwell would have  come out, but things seem daunting   now because of the manufacture doing the  20nm. is there a slight chance that there could be a maxwell 28nm? So now i have two video cards i have been looking at Asus 780 direct cuii or the Gigabyte 780 windforce ghz. Now which one to choose? Is the ghz chip picked? Which one has more overclocking head room? Hand on experiences with the cards i mentioned?

FYI running three monitors 1 1440p and 2 1080p.

overclocking headroom is just as random as the lotery, you can win it, or you can lose it, generaly a card with a higher factory overclock is a higher binned card and will generaly overclock higher with less mV. I hope they release maxwell with 28nm but i wouldnt get my hopes up

I think that the ASUS card would leave the most headroom, I've used ASUS cards in the past and I've pushed them to their limits and haven't caused any damage. I haven't used any Gigabyte cards but I hear that they are a little bit iffy. Imo for 3 monitors you should wait for the 6GB version from EVGA to come out in probably a month or so, or wait for 880 news.

i say go for The MSi 780 Lightning ,because with that one ,hello Over voltage ,witch gives you extended overclocking headroom ,stability when going too far ,and very good cooling due to the tri frozr ,you owning a power edition ,i think you already know that
