Summary: I've got a Windows Prem 7 64bit PC Intel i7, 8GB memory. Most video intensive program: Real Flight flight simulator. Ordered this card to replace a Sapphire Vapor 5670. To accomadate the card I upgraded the PSU to a FSP 400watt two rail Gold PSU.
Summary: This card is great. The other reviewer must have a bad fan. I replaced a dying 5770 with this card and know my machine is silent and the card runs cool. I can only hear the HDD now. Great card and worth the extra 10 or 20 dollars for the vapor-x
Summary: I have been a big fan of Sapphire cards for a couple years now and this card is yet another great entry/mid-level gaming card from that company. This card can play all my games set at the highest video settings.
Summary: Holy cow, this is the loudest video card... in the world. at IDLE. Do not buy this card or any other sapphire vaporx card, they are too loud, even if you change the settings to manually override the fan speed and minimize it, it's still unbelievably loud. Go elsewhere.
Summary: Sapphire Radeon HD 6770 – Potencia Concentrada Tarjeta gráfica de excelente rendimiento gráfico para cubrir de sobra nuestras necesidades de proceso actuales y futuras, por tratarse de un producto de alta calidad. Dispone de 1 Gb DDR5 de memoria y 860 MHz.
