Diamond 4890PE51GXOC ATI Radeon HD 4890 1024 MB XOC 256-Bit GDDR5 PCI-Express Video Card

I got this card to play UT3 and it *is* very fast. The problem was that the fan started buzzing loudly after only a few weeks. I've had a repair ticket in with Diamond Multimedia which they've ignored for the last week. I tried calling and nobody ever comes on the line no matter how long I wait. I tried their live, online "chat" tech support, but they're never online during posted hours. So if you buy this and if fails, your dead. Patti

============================================
EDIT: Here's a cut'n'paste from the online RMA/CustomerService page at Diamond Media. Note the dates - also the page shows live chat has been "offline" the entire time - even though their posted hours for "online" is 8-5 M/F (did this company go bankrupt and not tell anyone??). They don't even respond to my email... I'll update this if they *ever* respond to me!!!

I was hyped about this card as I heard rave reviews from my co-workets, but alas, it was not meant to be for me.

I got the card and plugged it in. Boot up and I came up in my OS (Vista x64 Ultimate) although extremely slow in the bootup (and I have my OS on a 60 Gb SSD so it normally boots very quickly).

Installed the drivers and that is where the problems began.

On the first reboot, it wouldn't come up. After a couple retries, it finally came up but it was EXTREMELY SLOW. Everything seemed OK other than being slow, that was until I enabled my second monitor. Then my system locked up. Finally got that worked out and still couldn't get my second monitor to enable. After trying for a couple hours, I removed the cared and put my dual NVidia cards back in and everything was back to normal.

E-mailed technical support at Diamond FIVE TIMES and never even got a response. Finally I got fed up and returned the card. Bought an NVidia GTX-260...Read more

The ATI 4890 is a great card. It performs equal to the Nvidia GTX275 while being cheaper. It is also very overclockable, with some models reaching 900MHz-1GHz.
It can also play Crysis maxed out at very high & AA at 1280x1024 with good frame rates. It also runs fairly cool - 50'C at idle (in a fairly warm 80'F room), and goes to around the high 70s'C at load.

My main complaint is that the card's fan is a bit noisy when overclocked and at load. At idle, it's fairly quiet, but at load you can definitely hear it through the computer case (my computer is about 2 feet away from me).

If you don't mind the additional noise, this is a great gaming card.
