Is the 7990 worth it?

RavenXXX2 · 16 Sep 2013 at 21:00

You do know the 7990 is dual GPU? I see no logic going from SLI to crossfire for similar performance.

I just got a pair of Twin Frozor 7950's for £300, I think they're gonna prove VERY good value then!! Esp when I clock the balls off em

I'm inclined to agree.

Are you sure my Battlefield 4 Vram thread has not given you twitchy fingers?

That's ridiculous. Second hand or brand new?

7990 gets my vote then, has 6GB so no need to worry about that lol, i cant see why it wont last a couple of years at 1080p, should play everything fine

Still thinking about it. I haven't made up my mind yet? was thinking of a slight downgrade to 2 670's. I need a few days to think this over

I *always* have twitchy fingers, but that's due mainly to the DT's

This the 7990 may be single card but remember it's still a dual chip so still uses crossfire and doesn't have built in frame pacing like a 690. You'll probably see temps rise across all components in your system as well with 80-90c in games.

JediFragger · 16 Sep 2013 at 21:02

7950's are proving to be insane value at present, esp when combining a pair :cool:

Not in my case. The Corsair AIR 540 is amazing for cooling. Not worried at all about temps. My lightnings never go over 65c

May as well plug my 7950 crossfire benchmark thread.

You'll be surprised, seen someone else who said they had good cooling but their 7990 was still hitting 90c in some games.

I know. I am a little confused on what to do. The one thing is the 770 lightnings are way too fast for what I play and do. so was thinking of either going 1 card and a downgrade with 2 gpu's or one. don't matter to me

darket · 16 Sep 2013 at 21:38

I would say a 100% no its not worth it, that is unless you like grabbing your bawls and just benchmarking, in a real world situation a 7990 doesnt really make any sense :-

1.They run stupidly hot.
2. unlike a traditional crossfire setup you cant disable crossfire so your going to be stuck with negative scaling in many games and dont expect AMD to fix this any time soon , if ever.
3. From experience its not a very stable card, once it gets hot things can get buggy
4. dubious quality reference cooler.
5. generally poor overclocking ability
6. Coil whine (to be expected in a dual gpu card)
7. A 7970 crossfire setup can be had for the same money and better performance plus when crossfire doesnt work you can just disable it.

6gb is a bit misleading. It's 3 gb per gpu, in crossfire which is 3gb effective total.

Drangueos · 16 Sep 2013 at 21:58

I think the 2x7950 still the way to go.

When the new cards come out we shall increase 7990's too £600-£700 region, make of that what you will.

If that turns out to be the situation across the board then the new cards must be complete crap

teppic · 16 Sep 2013 at 23:30

I was holding out for the new cards but I'm tempted to get 2x7970s. I like the idea of the 7990, but I think you'd need to put it under water to get the best out of it.

RetrogamerX · 17 Sep 2013 at 05:39

I was going to sell my 770's,but I've had had a rethink. My 770's while too powerful for my needs do everything I want them to do. I would be crazy to sell them. I did have a buyer for my 770's yesterday, but he backed out. I felt relieved he backed out. Why would I sell the best GPU's I've ever owned. I must have had a crazy moment yesterday to even think about selling them. Also the AMD news seems a bit disappointing. So there's no need to sell now.

FrankJH · 17 Sep 2013 at 07:43

I suppose it would be crazy from AMD's point of view to risk having an older generation dual gpu card in the same price bracket as the latest high performance single gpu card

Personally from the customer base that both cards are aiming for, I would suspect most customers would go for the new card (unless its total carp of course) - even without considering the heat issue with the dual gpu offering.

That price "rise" is crazily too much though imo, no matter what price the new card comes in at.
