Hey I am currently running 2 560ti SC in SLI and they are great cards. However i recently purchased a Avermedia Live Gamer Hd and in order for me to still play in 120hz on my monitor and record with the Live gamer I need to make a clone of my Graphics card to the Live Gamer. The issue is the to 560ti SLI or solo only support one monitor so I cannot use my secondary monitor for monitoring temps or when i live stream i wont be able to chat with anyone or use the internet. Would replacing the 2 560ti's with a 670 fix this issue? since i can run up to 4 monitors with a single 670?
A 670 can support 2 monitors but you won't be able to maximize your 120hz monitor when playing demanding games such as Battlefield 3 I am running a Gigabyte N670-OC/GD2 with 1150Mhz boost(1058 standard boost) with no manual OC and I am getting 63-70 FPS on it for BF3(looks fine on my 120 hz ASUS VG278H), you will need to SLI to maximize 120hz monitor with a 670.
As far as how cloning taxes your GPU I have no idea, I will try cloning my BF3 game play on my 37"HDTV today while playing. I got the 120hz because I can budget another 670 by the end of this month to SLI.
