Bump did not get any responses last time.
They have been running in my rig since the last post.
I also have a total of 4 of these 270 cards and there all Gigabytes.

I will throw in a free PCI-E riser cable for each GPU you buy.
I think $150 with free shipping is a fair price.
I can only ship within the USA and accept only crypto currency.

Also as for the above question each card runs between 380-400 khz.
