The ram has little to no relevance to hash rate. There are odd examples where the 2gb models have easier access to more shaders, such as the 6950.

But for 99% of situations, having 1gb vs 2gb makes no difference.

Since the calculation is done only on the GPU, the memory doesnt really matter. You can buy the cheaper 1Gb versions Smiley

And you should get at least 430 MH/s from a 5870 !!!!

Clock: 925 MHz
Memory:319 MHz
VDD: 1.07 Volts

I put them at 970 MHz when I have the air-condition on, and they reach 447 MH/s

Fiat no more.

If it's a mining rig go for the 1GB cards, for price reasons.
If you're going to be gaming as well as mining consider going for the 2gb cards as the memory will benefit your gaming performance.
