  1. You can't really just go buy specs. The second card looks better, but if the first has a much better GPU then it could be better. (a lower end GPU wouldn't have a 256bit bus, but if its an older model....) Which cards are you looking at, how much do you have to spend, and are you in the US?

    The price both of the graphic cards in my country is about the same..so i hope u can give me the best answer...Thanks a lot bro...im duan from malaysia... :)
  3. According to this chart, they perform roughly the same: http://www.tomshardware.co.uk/best-graphics-card,review-31723-8.html
  4. Best answer
    Given both are similar speeds, I'd go with the newer technology if they are the same price. That would be the 4670.
  5. thanks bro..u really help me ;)
  6. I agree, go for the 4670. Not only is it newer tech it has many up sides compared to the 3850. Less power needed, performs better with AA enabled, less heat, probably longer driver support, more ram, etc.
  7. The 4670 is a much better card.

    However if you want more advice you can post your system specs, price range, and desired performance here and we can advise.
