I did found something interesting tho ,"Joe Macri is Director of Technology at AMD… and in parallel is the president of the JEDEC committee which is involved in defining DRAM memory standards." not sure if still the case , but it would give them an advantage and influence as to where the gddr5 prices will go plus i imagine buying more dgrr5 in bulk does reduce price enough to make gddr3 redundant .As far as gddr3 bottle necking the card i highly doubt , gddr5 will provide higher bandwidth and lower latencies but performance impact will be minimal .
