Thats not an amazing deal, you could buy those brand new at about 340, (im assuming you're looking in the used maket, for brand new its a good deal) The gpu its not a bad deal though, vega 64 will outperform a 1660ti in most games but its power hungry and runs hotter. Keep in mind that for 200£ you're probably looking at a blower style card and those things can get loud sometimes
