I want to take a graphic card

hd 6670

How much money can you spend?

7770 would be a nice choice, 7750 if you're stuck for money.

o.k. no problem.First tell us your budget you need at least $80 to get a card that is going to be acceptable for gaming 6670/7750/7770 are the weakest cards i suggest for gaming.

Judging from his processor and RAM, a 7770 would be the sweet spot, I think, to the point where the CPU won't be bottlenecking the GPU. That's why I suggested them.

+1 i agree

I would also agree. I think going any higher than a 7770 would bottle neck that CPU. Personally I would update your CPU and then get a new GPU at a later time if you can't get both at once.

I am not really up on intel anymore but from what I could see that CPU is a socket 1155 and if true you should be able to find much better CPU's that would work with your motherboard. Then I would get atleast a 6950 or better depending on your budget. But it would help to know what make/model motherboard you are using first.
