Relatively new to this kind of thing so wondered is there much benefit to be had from overclocking my 5770, its the powercolor one, or should i bite the bullet and upgrade? I dont actually do much pc gaming more kinda just films. Also wanting to play 3d iso rips on my tv, which is 3d itself so would i need a 3d graphics card or does the tv take care of that side of things. Would i just mount the iso and play it with some software for example?
