If you're going to spend that much on someone's gifts ... You better find out what THAT PERSON likes
Get him a play station 4:-D It costs a lot cheaper than that.
I am putting my fantasy to work since my fiancee won't let me buy one so I keep dreaming about the day she surprises me with a PS4:-D
I found this link and they have some great ideas. I'm not sure where you are from but the link is from the UK. But I like the ideas, and it looks like the gifts are ordered from Amazon. If interested and live in the US, just plug gift into Amazon's US website.

If you know the person, you should be able to figure out what to get with that type of budget.
Depends on what he likes. If he's a PC gamer get him graphics card (if youre not tech savvy use this link) if he's a console gamer get him a PC. If he's a car guy well maybe a spoiler or rims, if he likes hunting get him a rifle or something nice like a gun or pistol. Ask him his interest and go from there good luck!
