Hey man! Hope everything's going well.
I think a single GTX780 should be great for just about everything. About as fast as your twin 580s, with double the VRAM and no AFR. What res is your monitor?
If you decide to upgrade later on, you could just add another 780 (it should be around for a while, don't expect the high end Maxwell until this time next year at the earliest).
Hey buddy! Thanks! A number of school/personal stuff kept me at bay for a bit, but I'm back. My monitor is 1900x1080. If the Maxwell is worth waiting for, I'm interested in it. Besides, it gives me time to save. I was wondering if Nvidia actually does release a dual GPU 700 series card and then shortly after releases the 800 series, whether or not I should just wait. I've reviewed their 2013/14 roadmap and it appears the Maxwell series isn't too far off.
