i dont know much about the latencies from gddr3 to gddr5, but i was hoping (actually praying lol) this will put it nearer to the 4870 (especially when overclocked) or at least 10% faster compared to a superclocked 4850 ddr3. guess it wont happen.
thanks dagger for ultimately crushing and stepping on my dream lol, just kidding, thanks for those computation btw.
im PSU limited (supposed to buy the corsair tx-series as replacement from my vx450, with the help from people from the psu section, thanks), and budget limited and considering theres a bunch of games coming out, my 4870 dream is slowly melting away.
