well for starters you chose the wrong brand for a dual gpu setup, with recent revelations in testing and FCAT dual AMD gpu;s don't have all that much of an improvement over a single card in perceptible performance increase. although amd are working on that, expect a few months before they release a driver that shows real improvement on frame pacing in multi card configs. Nvidia has been working on evenly spacing frames and smooth gameplay in multi card setups for much longer than just trying to achieve high "benchmark fps" like amd does
I am aware they have issues at the moment, but i consider it a longterm investment and I am more than happy to wait for the fix.
Thanks for your advice guys. Have really put my mind to rest.
I think, when i can afford it in a few weeks or months time I will get another identical gpu. If I'm not mistaken, two of these cards (which are designed for multi monitor play) will be quite the weapon
