Hi, I have an pretty old Intel Core i7 -4790 3.6 GHz with 12 gb a ram. I also have a ok graphic card and I can play the games I want smoothly. But when I want to do video editing with 4k videos my editing softwares are very slow and everything is buggy. I don't mind about final rendering time but while I work I sometimes can't even click on preview play on After Effect on some file with a little edit on it because it so laggy. I wonder if I bought 32 gb or even 64 gb ram if it would make a difference or my cpu would "cap" it? Is there other things I could do? My software and cache files are in a SSD. Thanks a lot!
