You can't use the second slot though (PCIe x1) as the card covers that, and note the bottom slot is PCI (not PCIe) in case you have or need to add some other card (sound or other).

You didn't mention 3GB or 6GB. I suggest getting a 6GB card. If the price is now too high, then I'd go with an RX-470/480 8GB card.

I like the 3-fan Asus Strix but I don't think the extra $50 can be justified. It adds cooling, but I don't know that it's needed.
