470SLI vs 7970

post #1 of 16

Howdy all smile.gif New guy to the forums smile.gif

I currently have 2 gtx470 in SLI. I'm thinking of selling both and upgrade to a 7970. Is it worth it? Will performance be the same as I had before or will it be a bit less since I'm coming from an SLI setup. Of course I can always CFX the 7970 but that would be later down the line. What you guys think?

Every game at 1080P with the exception of  a few games in the Total War series ran without a hitch for me. You don't need an upgrade. If you need some more VRAM, that's another story.

I mostly play BF3 right now (only on high), I can run ultra I can see it struggling (sudden drops in frames depending on action) I only play at 1920x1080. Also, my cards take up 3 slots each and I really want to upgrade my sound card (currently an x-fi xtremegamer). So I'm hoping the 7970 will be an increase in performance compared to my 470s.

2 470s at around 850 core will yield a higher fps than a single 7970. If your cards isn't watercooled then I'd highly recommend replacing it with a single 7970 if the heat and noise bothers you.

meh, not enough to justify an upgrade really. if you would call it that.


if you're really getting the itch, wait for kepler

Do you have AA enabled? BF3 eats VRAM like no other. And I could not see any difference between AA on or off.

OC both cards to between 800 to 830 if you can mem 1800. No need to have HBAO on in BF3 its a waste of time and takes alot of fps. Use FXAA instead and you will play on ultra easy.

Thanks for the tips guys! I'll do a bit of tuning in the bf3 settings and see what happens. I currently also have my gpu oc'd to 750. I think those tweaks will help it run better in ultra. I'll give it a shot tonight. I'll wait for the nvidia 6xx series to see what numbers they come up with.

Thanks again. You all are too cool for school smile.gif

GTX 470 SLI is beastly but in todays age it's hot, power hungry and doesn't have enough VRAM.

GTX 470 at roughly 800mhz is round about stock GTX 570 performance, 900Mhz on the core and they're not far off stock GTX 580 performance.

Overclocked GTX 470 SLI could hang with a GTX 590, but an overclocked 7970 smashes a GTX 590.

Personally I would sell the GTX 470's now before Kepler releases ensuring that you would get the highest amount of money back for them ( Kepler will cause there 2nd hand value to drop ) and move to a single 7970.
