Im selling my 2 780 classifieds as we speak on ebay looking for a change not sure which way to go would prefer to be able to water cool the card or cards im open to any ideas but would like to stay under $800 and I play at 5760x1080 so im thinking two possibly three 290x used or one 295x2 or one 290x 8gb and crossfire it later but i cant seem to find a water block for that card also not excluding nvidia just not seeing any big draw to anything they have as im more concerned about vram then actual processing power as that is the down fall on the 780s im getting rid of as far as psu goes i have a 1050 and a 750 that will both fit in my case so no worries there
