Upgrading from GTX 770 GB - New GPU for 2015

[Cr1tias]

I recently sold my Zotac GTX 770 2GB for about 200€ because it didnt meet my needs, it really couldn't play any games on Ultra with High FPS I think its due to the 2GB VRAM and now I want to upgrade.

I prefer Nvidia Cards I'm not really a fan of AMD and I really love Geforce Experience

I dont need one right away because I have my Xbox for gaming but I really want to play some games that are coming out this year on PC like The Witcher 3, Dying Light etc. and I want to run things like pcsx2 (PS2 Emulator) + some video editing here and there

My Budget is about 400-600€

My other specs:
i7-3770K
16 GB g.Skill RipJawsX Ram 4x4
Intel DZ77GA-70k Motherboard
CombatPower 750W PSU

I'm going to use at least 2 Monitors in FullHD and use a HDMI cable for playing Emulator Games on my TV which is also FullHD I dont think I want 4K anytime soon

I dont really want to OC but my Mobo supports SLI so if there is something good out there let me know

My country: austria
I really only buy from austrian sites since I dont own a credit card or paypal like for example:
Cyberport
E-Tec
Amazon

I appreciate any help and thank you for your time if you need to know anything else just ask

Here, this is all you need if you want something more powerfull than a 770.
this is the 3rd most Powerful single Gpu on the market from nvidia

well , if you're using two fullHD monitor for gaming , play games in max setting with a good FPS needs very high end card and best single gpu for this setup is gtx 980

doesnt matter if he uses 2 monitors he is not gonna run half and half of each, you need 3 for Surround or eyefinity.
a gtx 980 for this is a waste of money, a gtx 970 is so much cheaper and just as powerful.
