2x 560 ti's or 2x 7770's or 1x 7970?? Suggestions anyone?

I am planning on getting a video card(s) soon but don't know enough to really decide what is the best for me. I plan on keeping it for at least 2-3yrs so I don't mind paying a "little" more hence the 7970 option. I made my choice of the cards in the title based primarily on price and my PSU output. I have an antec hcg-750 PSU which should comfortably run the above cards according to several PSU calculators (rest of my components in sig). I know the drivers for ATI sucks now but obviously it will be improved. But from a performance standpoint, how much does a 2nd card really add and if the 7970 is much better, by how much? worth the price premium? I have a dual monitor setup but only plan on gaming on one but might extend to 3-4monitors in the future (office/wrk stuff only) O and although price diff between 560/560 ti/560 ti 448 core are minimal the power consumption isnt, any ideas there? Hope to hear from the community soon. thanks!

I just finished building my PC and fixing minor kinks here and there. Currently using Intel's mighty HD3000 driver lol. On a side note, I have an old LG246WP which doesn't have DVI but was given an hdmi-dvi cable to connect from PC to monitor's hdmi input. The resolutions are messed up and there seems to be no way in fixing it do you know why? I tried diff resolutions and refresh rates but it still looks like I zoomed into my monitor so it is off-centered and no corners are viewable. Plugged in vga cable, everything back to normal...weird.

Back to the orig topic, what you mean by mature drivers having 10-20% premium. Price or performance? Also 2x 7970 would definitely require me to swap out my PSU. Also the 7970 is a 3gb card, that's currently the max supported vram no? I am leaning towards ATI since 1 card can support 3 monitors while I need 2x NVidias for 3+ monitors.

Does anyone know what the current high end game uses in terms of Vram are? I haven't really been playing games on PC for a while and my last card was a nvidia 7950gt oc 512mb. I agree the 1gb vram might not be enough in the future but how soon? thanks

@fabe - thx for the suggestion I will do that

@ivan - does ATI patch updates to old games or just the "popular" oldies? And I am using this as a personal PC for now. I am not a hard gamer but do game occasionally when I want to kill time. But if I can't play BF3 or skyrim or etc on ultra settings it wouldn't bother me either. I will be happy somewhere in the mid/mid-high section. As long as the game runs smooth and has better or same quality as a PS3 then I am more than happy =)

thx for the suggestion ivan! this card looks beefy and isnt too big like some other ones. I read the reviews and it stated it had micro-stuttering/scaling issues in Xfire. what is that exactly? Also, the reviews at newegg all point to a fan problem so I may look for this card but from different manufacturer? I will probably get 2 for xfire and have almost $200 in change too instead of the 7970 lol. How does the 7770 compare to it though?

thanks!!

thanks for clarifying. how much faster is the 6850 than the 7770? would the 7770's PCIe 3.0 ever outdo the 6850's PCIe 2.1's dirvers/speed? In other words, is the 7770's speed due to the GPU or hardware? Also I read some bad reviews about overheating and fragile fan blades for the 460 x2 so I am going to stay clear of that...it is also really long 11.5in. I guess I will wait for a deal for the 6850s or 7770s depending on price, I guess whichever drops <$100 first since I will probably be buying 2.
