Hi all, I'm looking at getting a desktop that can handle VFX. I've got a laptop that's pretty average, and can manage Maya modelling, rigging, animation, etc. But I've just started learning VFX, and my graphics card can't even render the first simple excercise........

Hence I need a new desktop that's got a really super powerful graphics card and processor - but I've no clue about hardware matters. Does anyone have any recommendations of what make of desktop to go for, and what sort of graphics card to look for? Any and all advice would be greatly appreciated :)
