And one of the configurations we are looking into has dual Intel Xeon cpu's and four nvidia's graphic cards, similar to this:</div><div style="line-height: 21.3px; color: rgb(68, 68, 68); font-size: 15px; background-color: rgb(255, 255, 255);"><a href="http://www.thinkmate.com/system/gpx-xt4-2160v3-titan" target="_blank" style="line-height: 22.72px; font-weight: inherit; color: rgb(0, 104, 207); cursor: pointer; font-size: 12pt;">http://www.thinkmate.com/system/gpx-xt4-2160v3-titan</a></div><div style="line-height: 21.3px; color: rgb(68, 68, 68); font-size: 15px; background-color: rgb(255, 255, 255);"><br></div><div style="line-height: 21.3px; color: rgb(68, 68, 68); font-size: 15px; background-color: rgb(255, 255, 255);">The questions regarding the QE are:</div><div style="line-height: 21.3px; color: rgb(68, 68, 68); font-size: 15px; background-color: rgb(255, 255, 255);"><br></div><div style="line-height: 21.3px; color: rgb(68, 68, 68); font-size: 15px; background-color: rgb(255, 255, 255);">1. Does it support the gaming graphics cards like GTX 980ti or GTX TitanX, from previous post I know that gaming cards were unofficial supported but is the support is continued? As Mr. <span style="font-size: 12pt;">Filippo that informed that he will find a way to stop the use of gaming cards. </span></div><div style="line-height: 21.3px; color: rgb(68, 68, 68); font-size: 15px; background-color: rgb(255, 255, 255);">As the biggest reason we are interested in gaming cards is we could buy four gaming graphics cards for the price of one Tesla K40 and there are server configurations supporting them (GTX TitanX).</div><div style="line-height: 21.3px; color: rgb(68, 68, 68); font-size: 15px; background-color: rgb(255, 255, 255);"><br></div><div style="line-height: 21.3px; color: rgb(68, 68, 68); font-size: 15px; background-color: rgb(255, 255, 255);">2.
