Hey! I'm also thinking about building a rig around the region of £600 and I definitely agree with Redmint about Sandy Bridge! Definitely the way to go... my build is not *hugely* different from the above only that I've changed the PSU for a non modular, less powerful one but I believe its easily good enough to power a 6850 and an i5 which don't draw much power. Also its from *B grade stock* which makes it a good deal! I've also opted for an Antec 300 cause I've used it before and its simply brilliant in terms of cooling + looks! Thats my opinion anyway!
