Over-clocking video cards

[vonKrimm]

I am wondering if over-clocking dual GTX 275 video cards is smarter than over-clocking an i7 960 processor.  Digitalstorm offers both & was looking at their systems to get an idea for what I want TilDeath to build me for my new rig that I will be asking she-who-must-be-worshiped for Christmas.

Videocards usually offer very little room for overclocking. Probably the best shot would be to buy a 'golden sample' or 'OC' version straight from the factory.

Overclocking the vc will create more heat, this will in turn create higher noise levels from the fan which is typically very noisy in vc's. Third party coolers are rare and expensive.

I have overclocked my videocard but then again I have a fully watercooled dual radiator system to handle the heat. And even then the overclock available from the vc is minimal.

Moderate overclocks can be done to both without worry.  As stated, OCing a video card will add heat.  Overclocking a processor does not always add heat until under full load.  If you do not add voltage to your processor then your not adding heat until your running the CPU under higher loads.
