I have a top end rig (i7 3770K overclocked to 4.2GHz) with a top end GPU (GTX 690)... I'd love to run shaders but I always thought even on the fastest rigs, shaders make the game unplayable? Aren't shaders just for pretty screen shots? I'd be real excited if someone says I could run shaders and still get reasonable frame rates. Another question... using GPU-Z to see the specs, my video card says it has "1536 Unified" shaders built into it... what does that mean? I thought "shaders" was software, not hardware? Sorry, kind of a noob at this tech stuff.
