I could recomend this card but then I don't know what you want to use it for and I don't know if you computer will run this card. It would help a lot if you gave us some information so were not just guessing. The power supply is very important as this card needs a 400w power supply and it also needs 116w of power with a 6 pin power connector , some information would be helpful.
