1 out of 5 eggsWhat happened to support?

Pros: Fast card, excellent frame rates, got the job done..when it worked.

Cons: What happened to support? A couple of weeks after ownership, problems started to develop with this card. First thing I noticed was one color must have went out - everything turned blue. Then frame rates dropped to 10% on first core. Now, the card dies completely under load. It's a shame really. Now the nightmare has begun...I filled out a support form - promising contact within 1-2 days... NOTHING. I tried calling their support number and no matter what time you call, the call goes to a voice mail saying "We'll be back in 1 hours". Yeah right.

Other Thoughts: Has XFX gone bankrupt? Play hard = pay hard? I'm not sure what is going on with their support, but I may have to avoid XFX in the future.

Manufacturer Response:

Hello,

We're sorry you are having trouble with your card. Our website does indicate we will be contacting you within 24-48 hours, but as XFX is an American company, we also take American Holidays. New Years Eve and New Years Day are no exception. If you are still having issues, we are open today, Thursday, Janruary 2nd. Please call again and we would be happy to help you

5 out of 5 eggsWhat a thumper

Pros: Recently replaced my Sapphire Radeon HD6990 with this card. Didn't expect to see much difference in performance, boy was I wrong. Running BF3 on 3x 24" LG monitors with the game settings maxed out. My monitors almost can't handle what this card can dish out. The clarity is unreal. Noise isn't and issue either. Only under heavy and extended demands do I hear the fans rev up. I'm very pleased with this card. I would highly recommend it if it's within your financial range.

Cons: My only complaint is that it's dropped $100 since my purchase, that's electronics for ya.

1 out of 5 eggsoverheats

Pros: fast, lotsa memory, incredible bit rate.

Cons: i put two in crossfire and they overheated.

yeah, i have a xclio wind tunnel so no lack of airflow on my part.

Other Thoughts: these should come stock with waterblocks. especially at the price. luckily the vendor i used gave me back my money. i used it on two sapphire cards. they were cheaper and came with more adapters. i took off the case's side panel and now have a 20" lasko fan blowing on my machine whenever it is powered up. it would've cost me 450 dollars to use water instead of the less than 30 i spent on a house fan.

2 year warranty was quite a shock. i have other cards by xfx that are guaranteed for life, that's why i got these, i didnt realize they changed. ive also had sapphire in the past, i see no difference, but price and number of adapters. they look exactly the same except the fan decals and the name on the cards.

Manufacturer Response:

Hello Wizard, I see you are having trouble with cooling on your 7990s? Which card is over heating? individually they will run at the same temperatures as they will in Xfire, so i presume the top card has to be getting limited airflow... Or one simply has a bad fan or debris in the shroud. Email me at neweggsupport@xfxforce.com for help. Thank you

5 out of 5 eggsBlazing Fast

Pros: Cant find anything more powerful currently. Great for gaming at high resolutions. Keep in mind this card is BIG so double check to ensure you system has enough room to house it.

Cons: Must mention again is size, as this is far bigger than most video graphics cards, but then again it is literally double the card compared to anything else.

1 out of 5 eggsDONT BUY

Pros: Nothing good to say about this card.

Cons: Runs hot. Temps on cores under load go over 90. VRM temps 120. I bought two. They both burned out in less than 2 weeks.

Other Thoughts: Bad quality. No refunds. Replacement only. Waste of money.

5 out of 5 eggsPlease don't leave one egg reviews as responses :P

Pros: Powerful, quiet, cool.

Cons: Large and heavy (As you knew buying it), drivers need work, slight stuttering still visible in some games due to crossfire drivers, could use a little prettying up.

Other Thoughts: If you're going to respond to someone in a review, please don't leave a 1 egg review :P It lowers the overall rating of an item, not cool considering people look at the rating before buying.

4 out of 5 eggsBeast card

Pros: 1) Consumes more power than the other high end Nvidia cards
2) Runs pretty hot, fans stay pretty low so I made some custom settings with MSI Afterburner (no OC, stock setting). Idle without custom is 40-42C, under load I have seen it go up to 80C playing Blood Dragon.
3) Pricey with only a 2 year warranty
4) Have to dock and egg not for the performance, but the packaging. (see below)

Cons: 1) Consumes more power than the other high end Nvidia cards
2) Runs pretty hot, fans stay pretty low so I made some custom settings with MSI Afterburner (no OC, stock setting). Idle without custom is 40-42C, under load I have seen it go up to 80C playing Blood Dragon.
3) Pricey with only a 2 year warranty
4) Have to dock and egg not for the performance, but the packaging. (see below)

Other Thoughts: 1) Owned 3 XFX cards, have not had any issues thus far. Just like some other reviewers from the other brands my anti-static bag came unsealed. Crossfire bridge was in an unsealed bubble wrap pack. The quality assurance guys don’t need to rush on a $1k card!
2) Also minor cosmetic damage(minor scratches) on the gloss black cooling unit
3) With how hot this thing can get without adjusting the fan yourself, I wonder how long it will last under intense gaming. Quite a few people say that 80-90C is okay, but just because it can go up that high does not mean that you should keep it under that much stress. You never want to run anything under max stress.
4) Last but not least, lucky to get one of these.

5 out of 5 eggsGreat Card

Pros: Its a 7990 has a lot of power and is xfx

Cons: None for the card itself

Other Thoughts: This is my second 7990 and I have it crossfired with another one and I found it impossible to install the drivers with both of them in crossfire I thought it was a bad card but figured out that if I unplug either of the cards the drivers will install (I tested this with both cards) so if you have a 2 x 7990 and you have trouble installing the drivers from amd I would suggest that you remove one of the cards install the drivers and then install the other card again that's how I got it to work I think the drivers are a little buggy for the 7990's right now but hopefully the rumors are true and amd is fixing them
