5 out of 5 eggsGreat little card for a steambox

Pros: -Small. At 6 inches long, it is perfect for a small micro-itx build.
-Relatively quiet. I don't hear this thing during regular operation nor do I hear it when I'm playing older 3D games like Psychonauts or Tomb Raider Legends
-Plays all recent games at high/ultra quality at respectable frame rates.

Cons: -At load, it sounds like a jet taking off. The case for the system I put this in is really cramped and does not offer great air flow, so I can't really blame the card for this.

Other Thoughts: Great card for the price; even a better deal if you get the card with a rebate. Outperforms my GTX 460 SLI's (not by much) and uses less power. It may not be the perfect card for some, but it's the perfect card for my build/purpose. Thanks to this card, I have a "steam box" media center. Now to find a good front-end that lets me play all my games, switch to movies, and other applications using a game controller.

1 out of 5 eggs2 DOA in a row. Time to buy a lottery ticket.

Pros: On Paper it looks GREAT. Size was perfect for my case. Looks FANTASTIC. I hate giving one egg as Newegg has been very helpful in issuing RMA and XFX tech support was very knowledgable and the wait time on the phone was less than 3 minutes both times. So for support I give it 5 eggs.

Cons: Doesn't work. Wish I could give a review of the performance but with no signal I wasn't even able to install the drivers specific for this model from AMD.

Other Thoughts: Twice I called XFX Support and twice I was told I received a dead card. TWICE. My system is an HP H8-1010t with the Pegatron IPISB-CH2 Mobo. i5-2500 processor. Rosewill 630 PSU. 8GB RAM and an HP 2311x LED monitor. Am upgrqading from the HD 6570 OEM that has developed a very noisy fan. This HD 7790 was a perfect upgrqade for what I do. Updated the BIOS and tested PSU plugs. Even installed a friends old GeForce GTS 250 and it worked like a dream only I don't like the power drain and is so big I can't close the case without snagging the wire entrails that stick out. According to XFX the damage happened probably in shipping so I might just forget online ordering for this and just pay more by going to a local retailer though no one seems to have this XFX model. I now have missed the time frame for the rebate. I really wanted this GPU.
BTW I have been swapping GPUs so much this past couple of weeks and the PCIe plastic clip on the end just snapped off when trying to push out the video card for the 5th time. I guess it was in quite snuggly and will find out if it is really needed.

Manufacturer Response:

4 out of 5 eggsGets the job done

Pros: Runs games at pretty high settings, no crashing issues. Came with a cute door hanger "Do Not Disturb" for when you are gaming. Came with some free games too, what more do you want?

Cons: This card only has 1gb of ram, but so far this has not seemed to impact the performance. This card is large of course and takes up two slots, but makes that third slot unusable as well.

Other Thoughts: Go on AMD's website and get the catalyst drivers specifically for the 7790.
