sd card speed

hi guys, i got the RX100 for 2 months now, i love it but i have one problem.

i am using SanDisk 32 GB SDHC Class 10 SF-32NX, Read Speed 22 MB/s max. , Write Speed 10 MB/s min. ( it came with the camera ).

i don't need a memory card with more space but i need a faster memory card. when shooting in HDR mode it takes too long.

so here is question:

if i get the SanDisk Extreme Pro® SDHC™ UHS-I Memory Card that 90MB/s**write and 95MB/s read rate. will i benefit from that? i know that i will with a new pro dslr camera but will that be too much on my RX100?

thank you
