980ti Choices I was really keen on the Arctic Storm for a while but they weren't in stock at the time, and neither were the hydro coppers. I'm not sure the whole Arctic Storm hybrid air/water is great unless you really need to go on air for a while then push to water. That's what I was going to do if they were in stock, since I can't go under water properly until I move in a few weeks. They are the cheapest pre-built water cards however, so that's pretty intriguing. In the end I settled for the MSI Gaming 6G. Decent overclock, which I figure means that these GPUs are likely binned as higher quality. EK are working on a water block for these - they've already released on for the Strix. Once that comes in, I'll water block them. At the end of the day I'll have something like the EVGA hydro coppers at a somewhat lower price, but I was able to jump much sooner. I'll also still have the fan cooling setup that I can revert back to if I want to sell these later to someone without water, or if I want to use them in an air build later in their life if necessary. I presume that's possible - I've never reverted to air from water before. There was a comment earlier around VRAM vs the Titan X. Honestly, I think this is a non-issue for SLI users at least. There's nothing that realistically needs more than 6GB right now, and DX12 will completely change how GPU RAM is pooled. Instead of Alternate Frame Rendering, DX12 will assign parts of the scene to each GPU. It won't scale perfectly by any means, but the game developer in theory has access to the full sum of RAM across both GPUs rather than having simply two copies of the same game assets. 980Ti SLI therefore offers anything up to 12GB VRAM in DX12. It's going to be plenty between now and the next round of flagship GPUs I think. Game developers are going to have to primarily develop for the 99.9% of people with single GPUs.
