This may be a dumb question, but I am building my new computer and going to build a loop for the first time. I currently have a GTX 980TI and I am going to order the new NVIDIA card as soon as they are available. Should i run everything air cooled until i get the new video card and then start building the loop? If i build the loop now with my 980TI would i just be able to drop in the new card with the same water block or do you usually have to get a new block and change pipe placement?
