by techPowerUp! (Apr, 2009)There is nothing spectacular with the core overclock, it still allows for some fast and easy performance gains.
by techPowerUp! (Apr, 2009)Huge memory overclocking potential.

What People Are Saying Give it to me straight
Memory
by techPowerUp! (Apr, 2009)Since RV740 comes only with a 128-bit memory bus interface, GDDR5 can show huge improvements because it effectively doubles the memory bandwidth.
by techPowerUp! (Apr, 2009)In theory, GDDR5 offers twice the amount of bandwidth in comparison to GDDR3 at any given configuration.
by techPowerUp! (Apr, 2009)AIBs will design custom cards that can be cheaper or more expensive depending on the feature set like cooling, clocks, bundle and memory size.
Performance
by techPowerUp! (Apr, 2009)It offers the the highest performance in its class, at a fair price.
by techPowerUp! (Apr, 2009)I am sure AIBs will also look at alternative coolers to use on this card to either improve performance, acoustics or reduce the price.
by techPowerUp! (Apr, 2009)Rather than focusing on a small volume in high-end graphics, AMD has realized that a lot of people want cheap, affordable graphics that still can play most games out today.
Memory Type
by techPowerUp! (Apr, 2009)This card marks the mainstream entry of GDDR5 memory.
by techPowerUp! (Apr, 2009)For example we are seeing GDDR5 memory on the card.
by techPowerUp! (Apr, 2009)I am surprised that AMD has not fixed this problem in their second GDDR5-capable GPU.
Power
by techPowerUp! (Apr, 2009)A single six pin PCI-Express power connector is required to supply additional power to the graphics card.
by techPowerUp! (Apr, 2009)CUDA/PhysX. Although I didn't expect miracles out of AMD's move to the 40 nm process as far as power consumptions went, I am moderately satisfied with this card's power consumption figures.
by techPowerUp! (Apr, 2009)In idle the power consumption is not very impressive, I had much higher (in that case lower) hopes for a midrange 40 nm GPU board.
Overclocking
by techPowerUp! (Apr, 2009)The core overclock is typical of what I expect from AMD, I have no complaints, especially looking at the performance you could expect from overclocking this card.
by techPowerUp! (Apr, 2009)The memory overclock is simply stunning.
by techPowerUp! (Apr, 2009)The memory on this card further leaves you massive overclocking headroom.
