Best gpu for my PSU

Ok so i brought a 520w seasonic m12ii EVO for a i5 6600k build. Whats the best single gpu that can be used with this psu? Is there room for OC'ing the unlocked core i5?

There's no way of knowing what to recommend without your complete system specs.

Please fill out your system specs so that we can give you an intelligent recommendation, and be as complete as possible. How many fans, hard drives, type of CPU cooling, etc.

Computer isnt build but:
Core i5 6600k
Cooler master hyper evo 212
2x4gb kingston ddr 4
Z170 motherboard (don't know witch one yet but not the expensive rog ones)
2 case fans
1tb wd blue
Seasonic m12ii evo 520w bronze (not haswell ready)
Normal mouse and keyboard
6 usb devices.

It's definitely going to have to be an Nvidia card. ATI/AMD Radeons are too power hungry for that PSU. I'll let the Nvidia experts comment on what kind of GPU to buy, as I don't know the product line all that well.

As far as overclocking, I don't recommend it with that PSU. Once you get a GPU in the case, the PSU will almost be at its limit for available power, especially if you're gaming. There won't be much overhead. You need a little room to overclock, I'm afraid, and with that PSU, you haven't got much. I don't think an overclock will go successfully in your case. If you had a 700W or 750W PSU, on the other hand, you'd have enough headroom for a very good GPU, and still have room to OC.

Im thinking gtx 960 woth TDP 120w? Would that leave oc room. The idea is i want a budget card like 960 so that it has enougth watts left for a oc to 4-4.5ghz althought with air cooler it wont be a big oc. When i upgrade the 960 in 2-3 years, then ill think about a bigger psu? Does that sound ok

I ran your specs through a power supply calculator. It seems that the Skylake CPUs are less power hungry than I thought. The calculator gave a conservative estimate of 385 Watts of total power usage. That's a minimum, and as I said conservative. There are many factors which could increase that number very quickly.

Here is the website for the PSU calculator in case you want to fool around with it:

As for overclocking... Based on the figures, you might have enough headroom for a stable OC if you don't OC your GPU at the same time. Going for 4.5 GHz is a little extreme, though. Especially on air. You might get 4 or 4.2 GHz without excessive heat, but YMMV. It's hard to say. You might be lucky and have a well binned CPU that will get you to 4.5, who knows?

Just remember the old adage:
"If you can't afford to replace it, you have no business overclocking it."

Another problem is weather to go for a current get gpu or pascal/polarious since its so close to release, bht new cards cost more and im not rich. I somehow fis a r9 380 into budget at 230 usd but i wonder what next gen card i could get for that. No official info as of yet. Im desperate to build as it seems i keep holding off (core 2 duo HD5670 not fun). But i can only hope amd/nvidia budget midrange cards are out in a few months
