GPU for I5 4670K in mini ITX Motherboard

[Finair14]

Hello
i am building a mini ITX gaming rig and have decided to get the Intel core i5 4670k .I only have one GPU slot and so was wondering what the best graphics cards would be for the CPU. My budget is anything under 500
thanks

a gtx 770 windforce, or even better, the manli 770, (review here: http://www.youtube.com/watch?v=gcAEZzACpcw ) will perform excellent.
