Installed without any issue. No driver issues in Windows or Linux (Ubuntu Oneiric with fglrx). Very quiet - can't hear it over ordinary fan noise. Runs fine without a high-wattage power supply. Like most modern cards, this is rather large, but not unusually so - there were no problems getting it to fit. Runs like a 5770, perhaps slightly faster? Since most games are tracking an older hardware spec, it runs everything I've thrown at it quite nicely.

Overall, a very mature and satisfactory product

La tarjeta XFX AMD Radeon HD 6770(HD677XZNFC) mantiene una temperatura de 42 grados centigrados (42�) con el fan coller al 35 %, es realmente eficaz, eficiente y sorprendente, este producto combina armonicamente la calidad y la economia, tengo otra tarjeta grafica de la misma marca mucho mas costosa que a mi pareser no supera a mi nueva tarjeta 6770, recomiendo el producto al 100%

It works okay but to use it in the manner I intended (multiple monitors), I had to buy a $30 adapter for one of the ports. The product description didn't tell you about that.
