Hello All, So I have questions regarding the 780 Classified vs. 780 SC. I have been looking at the prices of both and with tax there is a difference of $100 between the two (cheapest SC, one vendor does not charge tax vs. the two vendors that have the Classified, and charge tax). I am planning on running two of these in SLI. Here are my choices. Classified: http://www.evga.com/Products/Product.aspx?pn=03G-P4-3788-KR SC: http://www.evga.com/Products/Product.aspx?pn=03G-P4-2784-KR Is it worth it to go with to Classified and spend the extra $100 (x2) or should I just go with the SC? Would I see a large performance difference between the two? Could I just OC the SC to the Classifieds MHz? Thank you in advance for the responses.
