5 out of 5 eggsWorking, and working well.

Pros: Very Easy to install and began working properly right away. Has been running almost everything I send it's way with good performance.

Cons: Unsure of whether or not this is really 4GB, has been running games nicely, but has trouble when I set the graphics level to High or Ultra.

1 out of 5 eggsNot Happy

Pros: Dunno yet. Didnt work

Cons: So it either came DOA, or it isn't compatible with my setup, which is unlikely. Installed drivers and all that good stuff. Also, the VGA port is too far to the left, so in order for me to plug my monitor in, I would have to mod my case... Very unhappy

5 out of 5 eggs

Pros: Easy install. Hardware detection and software install worked the first time around. Probably the easiest install upgrade I have ever experienced. Upgraded from 6000 series Radeon HD to 7000 series. (HD7750)
Visually noticeable improvement over Series 6000 Radeon HD graphics card. Improved Blu-ray display. Improved TV viewing on system through use of Slingbox. (FIOS TV)
Overall pleasantly surprised at how easy it all went.

Cons: No additional power connection available on video card. Only connection is through PCI Express. Only question why an additional power connection is not needed as specifications require a minimum of 400 watt power supply. Can the PCIe port handle that much power demanded by this card? Using a 600 watt power supply.
Leary as to why this card has 4GB memory and its efficiency.

Other Thoughts: Overall satisfied with the installation process and display improvements. Recommended.

1 out of 5 eggsissues

Pros: an eye appealing paper weight

Cons: After installing the card i used on board graphics to install and download all drivers, after which nothing was displayed on either of my monitors. It is receiving power, I know this because the fan on the card is working, but the card isn't recognized by dxdiag or device manager. So I suppose the cons would be:

Doesn't work.

Manufacturer Response:

We do apologize this issue you've experienced with out card. If you are still in possession of the card we can definitely help you troubleshoot the card. Though, to start off, it is possible that the BIOS isn't set to have an add-in PCIe video card as the primary display adapter, there may be a compatibility issue with the card which may require a BIOS update on the motherboard, or there may be something wrong with the motherboard's PCIe slot. It could also be possible that the card you received is truly DOA.

Try testing for those things first and if you continue having issues, please feel free to contact us at 626-330-4700 or by email at

Thank you,

PowerColor Support.
