Sorry - I did mean 7950. I don't know why I typed 9750...
To be honest, I'm not sure which model I'm talking about, I'm reading off a price sheet which simply reads "3GB 7950 Gigabyte OC" and "3GB 7950 Asus". I assume that the Asus model is the non-overclock version, as it doesn't mention OC in the name (as many cards on the pricelist). Therefore, I suppose, the Gigabyte would be the better option.
Though that's odd, because the Asus model is $18 more. Hmm, I'll have to find out exactly which models they are.
