Thank you all for your replies
The temps you posted are in celcius and are for the GPU? What fan speeds are the cards running , are they at max or less? There is not much to worry about for the CPU as that is not much of an overclock for that processor.
Yes they are in celcius and the fan speeds run at max using MSI Afterburner.
No. You're just making what you have run faster. Nothing wrong with that, but some 6950s have parts that are disabled and can be unlocked much like some AMD processors have cores that can be unlocked. They do more work using the unlocked parts. I don't think your 460 will perform anywhere near a 560ti or 6950, but don't worry about it. Just enjoy your free fps.
sorry hapikdo i wasnt clear my fault i understand my gpu couldnt be as fast as the 6950 i was just giving an example of an overclocking too match it with other specs if that makes sense
all been such a great help im very greatful
