yes you can. but if and when any overclocked 4870's come out the Mhz could be different depending on the model you get. example 1- you get a viziontel running at 700mhz(just guessing) and an msi running at 750,
the msi will go down to the 700mhz freq. same with the memory. 512 and a 1 gig, you'd only be able to use 1/2 of the memory from the 1 gig.
