Ok first off I know there backwards compatible. This not an answer I'm looking for. To which I will now as best I can ask the question. I want to update my Graphics card and need to know if I will need to update my MOBO as well. http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=9713820&SRCCODE=WEBLET03ORDER&cm_mmc=Email-_-WebletMain-_-WEBLET03ORDER-_-Deals&utm_source=EML&utm_medium=main&utm_campaign=WEBLET03ORDER this essentially the system I have with a few extras (I.E. 250 gb SSD ) The graphics card I want to get is http://www.newegg.com/Product/Product.aspx?Item=N82E16814126115. Now i've been reading the diffence between the type of connections. Summary of PCI Express Interface Parameters:
Base Clock Speed: PCIe 3.0 = 8.0GHz, PCIe 2.0 = 5.0GHz, PCIe 1.1 = 2.5GHz
Data Rate: PCIe 3.0 = 1000MB/s, PCIe 2.0 = 500MB/s, PCIe 1.1 = 250MB/s
Total Bandwidth: (x16 link): PCIe 3.0 = 32GB/s, PCIe 2.0 = 16GB/s, PCIe 1.1 = 8GB/s
Data Transfer Rate: PCIe 3.0 = 8.0GT/s, PCIe 2.0= 5.0GT/s, PCIe 1.1 = 2.5GT/s Now if I read this correctly the 2.0 will not adequetly handle the new card. I.E. there will be a significant drop in the speed in which the data is transfered? Am I reading this correctly? And by that. it means I will have to update my MOBO. And if so will I need to buy a new operating system. I had installed win 8.1 OEM Thank you for your time. And I hope I asked this in clear manner. My Apologies, I should have proof read my question a little better. The card I want to get is this one http://www.newegg.com/Product/Product.aspx?Item=9SIA57X4P21032
