Ok so i finally settled for the 7970 as within the next few months i will buy more screens, anywho, my PSU (850w) only has 2x6 pin connectors for the graphics card, im literally about to buy the 7970 but i need 2x8 pin connectors, do i need a new PSU or are there "adapters", like molex to 8 pin ect, if there are, can i buy them from overclockers or where from? cheers -Wiggy
