Dúvida quanto à placa de video!

[Héfer]

Olha só, em meu desktop pavilion serie slimline s5 com processador i5 já veio a placa de video: AMD Radeon HD 7450. Então gostaria de saber, se possivel o seguinte: se esta placa de video é melhor ou não do que essa que ja veio no meu pc. a placa é a: AMD Radeon HD 7750 1GB GDDR5 Sapphire Low Profile PCI-E.

e melhor ou não?

fico grato pela resposta desde já!

Ola amigo,

A especificação da placa que possui Hoje, esta dentro desse link: http://www.amd.com/us/Documents/AMD_Radeon_HD_7470-HD_7450_GPU_Feature_Summary.pdf

Ja a placa 7750 possui as especificações http://www.amd.com/us/products/desktop/graphics/7000/7750/Pages/radeon-7750.aspx

Que seria superior.
