GTX 650 ti or Radeon 7770

Go with the GTX 650 ti, it outperforms the HD 7770, if the price is close you should def go with the 650 ti  

you're also comparing a $105 card to a $140 card, so bump up the 7770 to the same price range and you can get a OC'd 2GB 7770, which depending on the resolution and games you're playing, may help or what else you plan to do with the card like multi-monitor gaming, the 7770 with 2GB might do better at the higher resolution.

googled some reviews and decided to go with the GTX 650 ti. i really like that it is quiet.

2GB model of the radeon 7770 is not available in my country. and the gtx 650 ti is only around $5 more than the radeon.
