Where are you shopping at? I can probably find a better card for cheaper.
I'm going to say the 64-bit bus will choke the GDDR5.

Thanks for offering to help me. I'm not buying now. I've firmly set my mind on Kaveri APU.

If I ever buy I'll buy in India because buying in my country will be convenient to me.

DDR3 has double the clock thoroughput, whereas GDDR5 has quad. Just by checking which has faster actual memory frequency you can sort them easily since the bandwidth packet size multiplied by the active ratio per signal, are equal. However, GDDR5 is said to have higher latency and error correction necessary for its normal operation, so that may cause some more lag. Also, GDDR5 runs hotter.
