Hello Toms

Ive come into some graduation money and went ahead and ordered a 1440p yamakasi catleap in white. Anyways, I usually play ultra on games and find now that my 6950's(910/1400 unlocked shaders___1____/__2___bios switch) just aren't cutting it and are unstable when overclocked and gaming at 1440p.

I understand 2 680's are usually more powerful than the 7970's on charts but my question is, when at 1440p 8x MSAA/ 16xFXAA, does the extra vram on the 7970 make it par with the 680's? I read that at higher resolution, the 680's run out of vram.

I mainly play battlefield but also playing Max Payne 3, Skyrim, and Diablo 3 (what a let down...but thats another thread).

I use Sapphire Trixxx to overclock.

I would like to get nVidia but if I can get the same performance for $60-100 less per card, then thats more money for a new cpu and another solid state.

Any input is appreciated. :wahoo:

I think U should consider 2x 7970 GHz edition its a beast

Or two normal 7970s since you already overclock. When overclocked they beat the 680 at high res.

or if you want the best... The sapphire 7970 toxic.is also being released soon. With a core frequency of 1200Mhz

yeah blow your grad money sounds like a good plan!

edited my jerk repsonse...

honestly if I was in your shoes and younger id likely do the same :) 

for me id get dual 670s, best bang for your buck imo... I prefer the green team what can i say...

Although if you can get a good deal on a 7970 then the extra gb of vram may help you with the multi monitors...

either way its still kinda hard to justify getting the 680 imo, again, aside from getting a smoking deal


personally im trying to pick up a 670 to replace my 560tis so i can have a little more vram... in terms of core power im satisfied with the 560tis but I can see vram becoming an issue sooner or later but honestly but i think many modern games scale back some of the resources based on the amount of vram utilized.

anyways didnt mean to hijack so have fun nabbing some gpus...

just buy 2 670s,they will max out anything at 1440p for less and yes 2GB is enough for
aa and stuff.
one more thing,for overclocking,MSi afterburner is the best software followed by evga precision.

2 x 670s is far better value than 680s or 6970s but if you are determined to get the extra few FPS regardless of cost I think in crossfire/SLi and the higher resolution the 680s and the 7970s are around equal, as the 7970s scale slightly better in dual card set ups and that resolution is just enough to use the extra RAM (but not making a huge difference). Battlefield 3 seems to favour Nvidia regardless though looking at benchmarks.

Thanks for the responses.

Do you think that getting the 680's in the 4gb flavor would make a considerable performance gain on the 7970s?

As in the 680's having the extra vram would allow it to outperform the 7970s?

And would it be worth another $70 a card for 4 gb?

The way I see it:

2 680 2GB - $1000-$1050

2 680 4GB - $1080-$1180

2 7970 3GB - $870-$950

If paying that extra $50-200 isn't going to give me performance increases then I would lean towards 7970's.

Maybe someone has the 4GB ones?

Thanks.


BTW I have been fooling around and testing all the games I play at 1440p and at that resolution, vram is really being eaten up. Anywhere from 4-8gb in different games.(8 in Max Payne 3!) Anywho, my guess is over the next 2 years, games are going to utilize that vram even more so I don't want to skimp now while I have money. :D

i hardly doubt that 4GB will make any difference over 2GB,as i said earlier,a gtx 670 SLi is the best solution for you.

Please don't throw out accusations.

I now understand that even though it shows 7.5-8 gb used, the amount is still halved due to vram being shared so my apologies.

Just because you don't have experience with game doesn't give you the right to force your opinion of 670's on someone.



If the 2GB of vram on each of my 6950's right now aren't cutting it, I see no reason to not upgrade in terms of vram. This is why I asked whether to get 7970 or 680 4gb. I now know that its not worth the money for 4gb but definitely worth it to get get the 7970's and overclock them.

At that resolution, they should be par or even better than 680's 2gb sli.

Thanks for the help.

On the topic of the amount of VRAM you can hit over 2GB today at 1080p in Skyrim using steam workshop mods. At 1440p and in the sense of future proofing I wouldn't consider less than 3GB, especially since crossfiring won't help you if you're VRAM starved.

Where performance is concerned you can easily hit 1Ghz core on a 7970 and outpace a 680 at stock (12.7 beta drivers). 1.1 - 1.2 Ghz can be achieved without touching the voltages depending on the card you end up with, further improving frames.

i didn't forced 670 on you,i just shared my opinion,a 670 beats a stock 680 for 100 bucks less,2GB runs well one of the most demanding game at the moment BF3 well even on a 3 monitor setup-

as you can see that 670 SLi works pretty good even on larger resolutions than your's so i think 670 is the best bang for the buck!
