at first 1 560ti was fine for a single monitor, then it was fine for 2 monitors but now iv got 3 well it wont take it so is it worth/possible just buying a cheap 560ti and SLI them or buy a better GPU. Oh and I wont be playing games with 3 monitors
depends, if you can sell your 560 ti then yes (new gpu). Especially if your playing indie games or generally a more wide variety of games. But if you cant sell it and you only play more retail games (BF3, Just cause, MOH, etc) then go with SLI.
sell off the 560 ti and put it towards a 600 or 7000 series card that supports 3 monitors :) 1 card is allways less of a headache than 2, with sli comes driver and game issues where the game only supports 1 card ect. but an upgrade to something like the 660 ti or the 7950 would be very nice
Always aviod SLI or Crossfire by default if you can. Never go out of your way to get 2 cards at once to link together. If you have a cheap low end card below the performance of the 560ti there is no benefit to linking it to an identical model.
Also remember that SLI or Crossfire is buggy, only uses as much ram per card as the card with the least amount of ram, and isn't supported by a VAST amount of games. Buggy, screen tearing, problems.
It's pretty much in BETA stages right now, so go with a gtx 670 or if that's to expensive check out a 7870. Logan reccomends the 7870 because it's so cheap for the awesome performance. You can find non-reference models for around $200-$230 American. If you're lucky even cheaper. Best card for the money.
SLI is perfectly fine. Crossfire does have driver problems. One card does have less issues then SLI. But SLI does work great.
the 3 monitors I have are 2 1440x900 19" and a 27" 1080 would a 660 be enough, I only use the 1080 one to play games
