Gigabyte HD 7970 3GB OC Crossfire vs EVGA GeForce GTX 680 Superclocked Sig+ w/Backplate

post #1 of 18

Hello,

I have this in Crossfire in my current build:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814125413

I just picked up two of these for $350 a piece:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814130780&Tpk=EVGA%20GeForce%20GTX%20680%20SC%20Signature%2b%20w%2fBackplate&IsVirtualParent=1

I have always used ATI/AMD cards in my rigs and I was really torn when I build my current one. I wanted to try something new and make the switch over to Nvidia, just to try it out. It is an expensive try out, so I went with what I always have the Gigabyte cards. I came across this deal (the EVGA posted above) and thought that I would take it and at least try it out. If I like them, great I will sell the Gigabytes. If not, I will sell the EVGAs.

Anyhow, I guess what I am really wondering is who do you think will win out? Which is the better multi-card set-up? Is 2GBs, compared to the 7970s 3GBs, going to be good for gaming now and in the future? I play games like Battlefield 3, Skyrim, all of the Total War games, ARMA games, Batman, you know, just games lol. I also use my rig for work which is web development, so I use the Adobe Creative Suite programs. I use 3 monitors for work (1920x1080), but only one when gaming.

Here are my specs:
mobo: Gigabyte UD4H
CPU: i7 3770k- stock 3.5-3.9
PSU: Corsair AX850
RAM: G.SKILL Ares 2x4GB
and, of course, the Gigabyte 7970 3GB Crossfire

Thank you in advance for any and all help and advice.

I am running 2 GTX 680s and think that the 7970s would be hard pressed to perform better. Espically with the drivers that AMD produces.

Here is a benchmark comparison I found on the 2.

I have read that AMD seems to do better with 3 monitors in gaming. Outside of gaming, running 3 monitors will not matter on either.

A lot of it depends on which game you are playing. Some are geared toward AMD and others toward nvidia cards.

Over all performance goes to the 680 though.

im pretty sure the 7970 would win, i have both 2 7970 by HIS ghz ed, and 680' msi, the amd i think preforms better in games like crysis 3 and even bf3, in my case that it, both great cards, but amd will take it.

IDK, My 680s work really well in C3. Every setting maxed at 1080p and no catching. Even at the start in the rain.....

sell the other 7970. you only need one for your setup even with 3 monitors. you can still max out bf3. my 7950 can.

build or buy a nas for your web development work if you don't have one. any extra can go to watercooling.

Thanks for the responses!

I think the only real "worry" I have going to 2GBs VRAM for EVGA, from the 3 GBs VRAM I have in the 7970s. Will there be that much of a difference in performance between 2 and 3?

If I am not mistaken, you will only notice the RAM difference in multiple monitor or really high res gaming situations. Even, then not sure you will notice a whole lot between 2 and 3.

Thanks! I am really torn on what to do. 2GBs of VRAM will be good for a few years, right? I mean, in the way of games in the next few years? Yeah, I don't plan on going multiple monitors, or even over 1920x1080 60Hz. I am pretty much tapped out right now lol.

Run benchmarks and see which get better results. Download these and run them on the same settings.

I think these 2 will test just about any card you can throw at them fairly.


If you are torn, let the score decide. Both cards will be very good for a long time.....

Make sure to let us know the results....thumb.gif
