bugs

Hi people! I'm new here First off, thanks for all the great info I've got from this thread so far! You guys are awesome! So, I'm kinda new to this whole laptop upgrading thing but I have a couple of questions! Could I put 32gb ram in the 2570p? Also, could I use the expresscard for a desktop sound card instead of eGPU? Thanks!! Also, if anyone knows where to get any of the compatible quad core GPUs for cheap, I'd love to hear!! Thank you!
