I am preparing to build a machine for wysiwyg and make the big purchase. In the tips and tricks section of the website there is a section called Selecting Hardware for a WYSIWYG Workstation which states: Using multiple video cards in one system via nVidiaâ€™s â€œSLIâ€ or AMDâ€™s â€œCrossFireXâ€ technologies is supported by wysiwyg, but our benchmarking has only shown a 15-20% performance gain when using two cards of the same type in one system (versus using only one such card). What does "supported by wysiwyg" mean? With modern graphics intensive games the game is programmed to take advantage of SLI. Is that what "supported by wysiwyg" means? Has wysiwyg been programmed to use SLI? The reason I ask is a GTX Titan X costs almost four times the price of the GTX 970. In most gaming benchmarks two GTX 970's OC'd and running in SLI will be pretty similar or better in results to the GTX Titan X (to be specific, in maximum fps, but not in lowest fps, which makes the GTX Titan X still a better choice if you can afford it) at a significantly lower cost. I am trying to gauge whether I need to go all out so to speak. Most of the shows I design will use around 200-300 fixtures with lots of set pieces and I would like to use capture card and get my visuals onto some screens. I can't see within the next two years needing more than 500 fixtures in a single show. I want the strobe speeds to look correct and not lag too much when I have fixtures pointed toward the camera as I have seen it do on my friends machine. Will the GTX 970 oc'd cut it as a single card? Will I get a decent increase from SLI? 20% increase with two GTX970 in SLI might put it well ahead of a single GTX980 without costing much more. Thank you!
