What People Are Saying Give it to me straight

Applications

This is very nice for overclockers because they can now change both voltages via software.
by techPowerUp! (Apr, 2009)
Voltage controller does not support software adjustments.

Gaming

Thankfully, several of our game tests were receptive to the multi-GPU standard, and responded with decent performance increments, which scale up with increases in resolution.
by techPowerUp! (Apr, 2009)
Over the years, the technology has matured many fold, and has garnered support from the game developer community in a decent measure.

Price

Due to the improved PCB design Powercolor can offer their HD 4890 PCS for the price of a normal reference design board, $249.
by techPowerUp! (Apr, 2009)
It is a neat 10% faster than the reference-design accelerator, and is one of the fastest accelerators for its price.
by techPowerUp! (Aug, 2009)
As a result PowerColor can offer their card at the same price as normal reference design cards which makes this an interesting deal for many users.

Performance

At 1920 x 1200, performance increments of 92.3%, a near-perfect scaling is observed, which is impressive indeed.

8.0PowerColor's HD 4890 PCS can impress with great performance right out of the box.
by techPowerUp! (Apr, 2009)
The card offers considerably improved performance over the HD 4890 reference design and can beat the GeForce GTX 280.
by techPowerUp! (Jun, 2009)

Power

Two six pin PCI-Express power connectors are required to supply additional power to the graphics card.
by techPowerUp! (Apr, 2009)
Power is delivered to the card via two six pin power connectors.
by techPowerUp! (Aug, 2009)
This means that any decent power supply should be able to power such a dual HD 4890 rig.
