i like the 6670 but for future reference can someone tell me why the GDDR5 card i listed is better then the DDR3 card i listed even though the DDR3 says 2gb and the other 1gb. I will get the 6670 if i can but will a PCIe 1.0 x16 work with the PCIe of the 6670?
GDDR5 is Faster memory that is designed to be used on a graphics card. It is much faster than standard DDR3 memory but is not suitable for use as system memory. Because it is faster, it allows more data to be transferred between the GPU and memory resulting in the GPU operating on more information in less time. That improves performance.
