gtx 760 vs 1050? the same efficiency 40% cheaper? where's the catch

Hello. I have such a computer here
Intel Q6600 @ 3.2Ghz
Asus P5Q SE2
Gigabyte HD7790
Kingston 8GB 4x2GB
Antec VP 500W
I know that the processor will severely limit the card but for a new platform with 8gb of RAM at the current price of that framework I would have to give PLN 900. Thank you stops. Maybe in the summer when the ram falls and new Procki come in and the old ones go down. However, I am tempted by this graphic. I have a radeon that sits terribly on my processor (specifically its drivers), I watch people on YouTube overclocked q6600 play at the border of smoothness (but still> 30fps) in games like watch dogs 2 or Need for speed 2015. And I cut everything. Currently observing gtx 760 auctions

It seems to me that the price should close to PLN 380, not bad cooling. admittedly from gigabyte but at least a lower price, and someone knows maybe they have improved the quality a bit compared to the previous decade.
Meanwhile, 1050 in identical cooling costs PLN 550. Of course, I've looked through a lot of tests. 760 performance close to 950, 950 close to 1050. It is known that the game depends, sometimes better sometimes worse, each game uses the resources available on the card differently. after all, similar results in 3dmarks. Now the question is: where's the catch? worse compatibility in the upcoming dx12? weaker driver support because these are "old" generation cards? ...
and most important: take or not take?

Are you comparing the price used to the new one and are you surprised that the first one is cheaper?

GTX1050 is more than twice less energy consumption (cooling can be smaller / quieter), by the way better "multimedia" - eg HDMI in a higher version, encoders and decoders h.265.
If you don't use it, it won't matter to you ...

"Raw" power in games will be similar, with an indication of a newer chip.

In the end I bought a gigabyte gtx 960 2gb with warranty until the end of February if necessary. for 440 PLN + 18 courier. what do you think is a good deal? on ultra gta 5 and in the latest ac you can see the difference between 2gb and 4gb but in a very large majority of other games in 1080p resolution there are no differences and sometimes 2gb is even better. I'm worried about a year or two. at most I will be pushing further

Yes, the price is right.

Don't worry about such a price , gtx 960 should hold well at least until the release of the 9th generation consoles.
