Matching GPU

Hi, I currently have a Asus B85M-K motherboard with a I5-4460 3.2 GHz CPU. I was wondering what would be the best GPU match with this configuration. I'm looking for a decent gaming GPU, that isn't too expensive.
Thanks

What exactly is ''too expensive''? For me, it might be $200 for you, it might be $100 you should tell a range or a specific budget so it's easier to give you recommendations.

Also, can you please tell me what's your current PSU? The newer graphic cards need way more power than the older ones so you want to make sure that your current PSU will be supplying enough power.

I would highly suggest posting your price range as what had Gladdy said, it might be affordable for me but too expensive for you.

My current PSU is a Corsair CX500M 500W. I guess thats enough power to run a decent GPU with my configuration? My price range for the new graphics card would be between 300-350$. Thanks for your help guys.

Depends on your budget bro. Any GPUs that are above GTX 600+ series are compatible. But as what the posters above me have said, it all comes down to your budget.
