So I have a asus m4a785tdv evo motherboard and Im planning to buy 2 7850's. I know these arents the best cards for mining but its a sort of experiment.

Anyways, im planning to buy two of those cards but the problem is that I have one 2.0PCI-E x16 slot and a 2.0pci-e x4 slot. Can I directly plug those gpu's on my motherboard without loosing any speed from the gpu that wil be going in the x4 slot or would I have to guy a pci-e riser cable?

You will have NO problem. A GPU only needs X1 PCIe to run at full speed for BTC/LTC/etc  Wink

Personal anecdote. Just found out about 1x to 16x risers and found out they were all sold out on most sites. So I went to ebay to find ridiculous prices and like a month shipping from China. I almost got caught up and bought one. Glad I didn't, just looked at my motherboard to find my 7850 completely covers the 1x slot.

I guess moral of the story; dont jump on bandwagons, and know your hardware.

That just means you need to put both cards on risers!

You can still run a riser out from underneath the 1st card.  It won't allow for as much separation but it still works.

Ahhh, good idea! I actually have an extra 6670 sitting around, not that much power, but I was gifted it awhile back so no loss really. Thanks for the advice!
