as the the thread suggests, I am looking to upgrade from my GTX 560ti SLI setup, Mainly because of the VRAM shortage not allowing me to max out some of the newer games. I game at 1440p and like to run games with all setting on high, however with the new games coming out i find it difficult to do so and always have to compromise somewhere.
I know replacing one 560ti with a different brand and spec 560ti may cause some SLI issues, but ive also heard that a 560ti SLI setup runs pretty close in terms of performace to a single 660ti, will the outlay be worth the performance?
If 560 SLI runs pretty same, you should go with 660 Ti. Because keeping a single card is always better than SLI/Crossfire.
2 GPU produce too much heat, have more power consumption. And you know that if a GPU is heated than it effects its performance.
And also in future you can add 1 more GTX 660 Ti if needed.
