Hi Saikat,<br>
<br>
Would you please let me know which application / functional component of cryo-EM data processing? I will do my best to provide guidance where I am able.<br>
<br>
Thank you.<br>

Hi cryo-EM community members,<br>
<br>
I would like to know if anyone is using or benchmarked the Titan RTX card for cryo-EM data processing?<br>
<br>
Is it worth the price of the card (almost twice the price of the RTX 2080Ti)?<br>
<br>
Thanks,<br>

Dear Community,<br>
<br>
A couple weeks ago there were a couple of helpful discussions on the comparison between different GPUs. I am wondering if people can provide some insight into the newly announced Titan RTX
<a href="https://www.nvidia.com/en-us/titan/titan-rtx/">https://www.nvidia.com/en-us/titan/titan-rtx/</a> The 24GB memory seems to be particularly appealing.<br>

Dear Jonathan,<br>
<br>
I am referring to the standard cryo-EM data processing packages like<br>
Relion-3-beta, Cryosparc 2, IMOD to name a few.<br>
<br>
Thanks,<br>
