The issue with this card is that the cooler doesn't exhaust the hot air out of the case. This type of cooler design pushes cool air down towards the PCB and out the sides, at which point it's normally exhausted out by the case fan. BUT, when running in Crossfire with two of these cards, the #1 card (at the top) is basically blowing the hot exhaust air down onto it's cooler making for very high operating temperatures. In my experience, the #1 card easily runs 10-15c hotter than the #2 (bottom) card. This means under high GPU loads (even at stock 900mhz clocks), the #1 GPU can hit 90c and eventually reach a point where the card will disable itself because it exceeds heath thresholds.
The only solution I've come up with to work around this issue is under clock the #1 card to 875Mhz and have a case fan blow cool air down into the gap between the cards. Doing this, I can keep the GPU temperature around 87-88c under high GPU loads. This is obviously a design flaw in the cooling for this card as I've swapped my two cards and this pattern always happens to the #1 card.
So, please heed this warning if you're looking to run this card in Crossfire: DON'T!
If you're looking to run this card by itself, then by all means! It's a fantastic card and great for overclocking :)
I like the blue protector shields over the HDMI and DVI ports, and for the PCIe connector. Nice touch.
This card is fast, though your case's interior bay has to be wider than 10" for this to fit. The Antec 300 case does fit, but space is tight so route any cables properly.
Lastly, Amazon.com did not add any cushioning material to the package inside the outer box. When I opened the outer box, I was surprised to see the Gigabyte box with no protection (the plastic air packs). When I removed the card from the Gigabyte box, I noted the front plate was slightly bent at the bottom. I cannot determine if the shipping caused this or if the people packaging the card screwed up. Given the styrofoam being secure around the main card didn't affect the fans, and that the top of the backplate was not bent (just the bottom), I'm thinking that somebody at the manufacturing plant accidentally bent the bottom of the plate. Hence my knocking off one point. The card was secure. I just hope this isn't a bad omen, but despite the lack of air packs securing the Gigabyte box, enough circumstantial evidence is making me think it was at the factory.
There are many technical reviews posted on these video cards if you're interested in specifications, but I'm trying to write this review from a more common sense perspective. If you're buying a card for general gaming then most any ATI or Nvidia card which gives you the most power vs. price becomes your best choice. If you mostly play one game, then there are plenty of on-line reviews which benchmark performance with specific games, buy the most performance you can afford for the specific game. But what about for an image or video workstation?
There are two types of power/speed you need to be aware of. There are programs which task the GPU (graphic processor) directly, Adobe has done this with CS4/CS5/CS6 and this tasking greatly speeds up certain tasks. Other manufacturers of software such as gaming, file managing, imaging, video rendering and more directly support/task GPU's. Know your software. Adobe and others will have a video card support page providing a listing of specific GPU's certified to work with their product. You are well advised to by the most powerful card on this list within your budget.
Then you have regular rendering of screens. The more video resolution your monitor has, the more power you need to render screens.Read more ›
Overall, I'm happy with this GPU. It dropped right into my Gigabyte MB and required zero additional drivers to work in OSX...perfect :)
