well just giving you some options, drop the x and get the plain version with some water cooler
I been reserching video cards for last 4 months, I wanted the new nvidia maxwell card but the got delayed til 2015. The titan black is way overpriced as is the r9 295x2. My 2nd choice was the gtx 780 ti but those prices are still not in my budget since i needed two cards. I didnt even consider the amd card due to power requirements but poking around craigslist I found what I thought was a good deal, so Im happy now.
What monitor are you running?
