men - outra vez, eles testaram o modelo com DDR3 e ainda por cima OC.
com ddr3 essa placa mesmo só com 512mb era superior, mas assim é claramente inferior, a Bandwith caí para quase 1/2 da DDR3.
Vê este post de um tecnico que trabalha na XFX(pelo menos é o que ele diz):
"The differences between DDR, DDR2 and (G)DDR3 should not be underestimated.
For example, I have seen a GeForce 6800 GS with 128MB DDR @ 720MHz gets 3800 points in 3DMark05; in comparison, 6800 GS with 256MB DDR3 @ 1000MHz manages 5000 points in the same benchmark. A lot of that is due to the extra RAM on 6800 card, but the extra 280MHz memory speed gives it a lot more bandwidth and thus, better performance.
In general, if given a choice between a card with DDR/DDR2 memory and DDR3, *always* go for the DDR3 model. It may cost a bit more, but that card will run faster and will have much more capacity for overclocking."
