Why does my tablet crash using Chrome/Internet Explorer?

Every time I load a new webpage the tablet freezes momentarily (about 5-10 seconds) and displays an error message asking if I'd like to 'force close' Chrome or 'wait' or 'send feedback'. This happens 95% of the time opening new tabs or just clicking links from Google. I normally click 'wait' as it sorts itself out.. eventually... but it's a bit of a ballache. Having paid $600 odd on the flagship tablet from Samsung I kinda expected glitch free browsing. Any ideas?
