So I have an evga 8800 GTS 320mb card. I want to upgrade by I am considering getting another one as they are pretty cheap now and SLI them. The only thing is my current card is the SSC version which is basically an overclocked card. I cant find any place to buy another SSC card of this same model. Would it be ok to get another card but not the SSC version? Or will I run into problems when I try to SLI them? I will be running on a 680i board. Thanks.
