Thanks Dark Mantis, much appreciated.
Just had a reply from asus support regarding the same question for 1 for their motherboards. Thought it was very professional
Dear Valued Customer,
Thank you for contacting ASUS Customer Service.
My name is Jany and it's my pleasure to help you with your problem.
Generally, the PCI-E slot on the motherboard is designed for graphic cards. But if you have some other PCI-E device and boot up from the onboard VGA, you could have a try.
