I have a Biostar N68S3B MoBo and I want to purchase a graphic card for it soon. The problem is I don't know which version of PCI-E it has, whether it is 1.x or 2.x. I couldn't found something strong about it. I asked E-Support guys but not reply from week, I think they are too confused because most of the time they reply within 24 hour and this time no reply from weeks. Can any one here help me to find out PCI-E version of Biostar N68S3B MoBo ?
