I cannot give you any advice off the top of my head, simply because I do not follow "the latest and greatest" on a daily basis. I know a site like
Tom's Hardware - Computer Hardware News, Tests, Ratings and Reviews should be able to help you out, although personally I have not used the site for many years, simply because I have not had the need to upgrade my systems. I am sure if you do a little searching with your favorite search engine, you will find similar sites with the information you want but I think the Tom's Hardware site would be a good start in my opinion.
