Unexpected Windfall = Insane new build

[confusedtx5]

You're really comparing 1x 30" to 2x 24" monitors? Of course the 2x monitors are going to work better with a 5-toon layout. What you really should do is 1x 30" and 1x 24" if that's your concern.
I run my alts on the secondary monitor, and the main on the 30". alts are scaled down so much its barely readable though. If I was smart, I would put the main on the 24" monitor, and the alts on the 30", but I have 2 secondary monitors on either side of the main 30" so that would feel wierd. 1x GTX580 1.5GB can handle 5 windows @ 2560x1600 @ low quality, but I'm constantly hitting the vRAM barrier.

The majority of website aren't designed for that much screen real estate. hit windows+right(or left) arrow to put the browser up to one side of the screen. Makes things much more read-able, or just keep it windowed.
One of the bonuses for 30" monitors is being able to have up to 4 windows open, sitting next to each other, and still have plenty of space inside the browser for viewing.
