Choosing between 780ti and 980

Hello guys, i have a quick yet elaborate question.

I'm selling my current Sapphire R9 280 (i've had enough of AMD's crappy drivers and unjustified temperatures) and i'm planning to upgrade to a much better nVidia card.

First off i'm going to say that i will completely avoid the 970 series because of their "marketing error" with the malfunctioning 4GB vram that is actually just 3.5 + slower 0.5 and 56 ROP instead of the advertised 64. I am not going to spend my hard earned money on a badly done product.

So, naturally, i managed to narrow down my choices to these two: 780 Ti and 980.

My current specs: i5 4690 @3.9GHz, 8GB 1600MHz CL7, GA-B85M-D2V

What i know so far:

780 ti is older, has better driver support, less memory but wider memory bus, higher TDP and so on.. but the most important aspect is the 240/48 ratio of texture units to ROP, and the high number of CUDA cores (shading cores), 2880.

980 is newer, more efficient, newer (thus lower quality drivers, for now), more memory but lower memory bus (goddamn compromises), lower TDP, and a much more common TU-to-ROP ratio, 2/1. (128/64)

My question is.. how does that translate in 1080p 60hz gaming? I prefer playing at 1080 with constant 60fps (if i don't get 85+ with vsync off it's not going to be stable enough after i enable vsync, so i keep reducing graphical options until i know there's a good 30 frames of headroom above my vsync limit)... i never use any kind of AA, DOF, blurs but i love maxing textures, AF, shading, shadows, lighting and so on.

So, main question: Isn't the 780Ti more equipped for low-resolution high-fps gaming (given its high ratio of texture units over pixel units), compared to the 980 (given the lower, more common ratio of texture units over pixel units)?

It seems to me like the 980 is more suited for 4K or multiple monitor setups, things that i won't use in any of the near future.

Also, price comes in to play as well. Initially i decided to pay 2650 ron ( 662$ ) for the 980 g1 gaming from gigabyte, but then i realised that i could buy the ASUS 780ti directcu2 1020Mhz version for only 1950 ron ( 487$), and the internet tells me that the performance difference is only about 7-9% between the two cards.

I do know the fact that all the specs regarding VRAM have a small impact over fps, but i'm interested in why nVidia chose to modify that texture unit-to-pixel unit ratio so much for the 780 ti.

Also, is there any real difference (except the frequency, which i can modify myself anyway) between Gigabyte's 1279MHz 980 and the g1 gaming version (1329 MHz)?

Thanks for taking the time to read all of this :D help me not waste my money, thanks!

Well, i didn't say that cards made for high fps on high res aren't suited for high fps on low res. I just said that they might be made to work better on high res because of the higher amount of pixel units relative to texture units.

The reason why the 780 Ti is appealing to me is the high amount of texture units relative to pixel units ( 240 / 48 ). That would indicate that the card is made to handle higher settings on lower resolutions, rather than lower settings on high resolutions ( like a 128 / 64 ratio would indicate ).
