[blazer]

1. with ATI Radeon HD 6970 processor 900 mhz and 2gb ddr 5 memory, 256b bus.

3. with ATI Radeon HD 6970 processor 900 mhz and 1gb ddr 5 memory, 256b bus.



1 and 3 are good, 6970 = More shader process @ higher clock speed = Faster.

I doubt the memory size makes much of a differences, probably look at the price difference?
