Some makers are incorporating GDDR5 on their GT555M offerings while others like Sager NP5175 are using GDDR3.

See MSI GX680.

Slower memory on a faster bus vs faster memory on a slower bus.

So what's better? Slower memory on a faster bus or faster memory on a slower bus?

[Maverick494]

in this case, slower memory:

the DDR3 version has more CUDA cores than the GDDR5 version. Both have the same theoritical fill rate.

CUDA cores make the Nvidia card tick for the most part. Plus the memory bandwidth is only slightly lower than the GDDR5 model, which can be overcome somewhat with a memory overclock.
