Lulz. Thats it. I buying used 980TI soon. My hair botak already and no upgrading is killing me. Hahahaha.

haha well depends if for long term saving investing best high end card give you more value save money and gets to enjoy every new epic game with best feature available.

like me for example i use my GTX480 for 7 years and still able to manage play decent setting until it die . worth every penny that price came out and time to upgrade this GTX 1080

Wow... what's with all the toy looking coolers from the third party AIBs?

I enjoyed my 980 Ti for the past 11 months, so I don't mind its value is affected by the 1070 or 1080. Those who buy Pascal today will be the same too next year. Exciting times for GPU advancement.

Coming from a 280X previously, the 1080 gain isn't enough for me to upgrade, moreover I'm still gaming on 1440p.

ever since my Vapor-X doesnt fit on some case, its hard for me to buy those thick 2.5 slot GPU. 

I'm on 980 Ti now, and it barely do 60fps in the poorly optimized The Division. I switched from 280X because it's not powerful enough for BF4 @ 1440p ultra.

People need to understand a few things regarding 1080p vs 4k.

4k monitors/TVs aren't actually 4k in resolution, it's actually 3440x2160 instead of the actual 3840x2160. Stop being duped by Hollywood.

3440x2160 is an EXACT 4 times increament of resolution over 1920x1080. All a monitor or TV need to do is to quadruple the FHD image into UHD without any further calculations. This is different to when 480p was upscaled to 1080p, or 720p going to 1080p. Neither 720p or 480p were linear increase in pixel count when being upscaled to 1080p, which is why 480p often looks like horseshit in FHD (even with the best post-processing scaler).

1080p looks like 1080p on a "4k" screen because it's a linear increase, not because your "screen looks smaller". You can play a 1080p image on a 120" screen through a 4k projector, you'll actually see next to no difference between that and a 1080p projector to a 120" screen assuming all post-processing are disabled. Of course, the 4k projector would have much more advanced technologies to further boost a 1080p image to look even better than it originally did. This goes the same for most of the high-end "4" (UHD) TVs on the market now a days.

All a smaller screen does is that it has much higher ppi/dpi, which will help mask aliasing issues, giving a perception things look sharper and better. The latter of which is actually down to panel quality as small panels are much more easier to produce in high quality than big panels are.
*EDIT*

As a side note, instead of aiming to go for 4k60p, I heavily recommend people to go for a 1440p (QHD) at much higher refresh rates if gaming on PC is the main target. 1440p at 120hz (or 144hz) is a whole new level of improvement IMO. Even better if one can have Gsync, that's godlike upgrade there.

I'll keep drilling this point, 1440p @ 120hz (or 144hz) with Gysnc is the best sweetspot for PC gaming now. 4k60p is just 1080p60 with sharper visuals, of which does almost nothing to improve gameplay.
