my problem comes out of the following: I'm owning a 'MSI P45 Neo 3' Mainboard. The 100% type I haven't checked yet, I'm about to do it as soon as possible. For sure is that it's already about four years old and as I plan to upgrade - if possible - only the graphic board.
So here's my problem: from http://us.msi.com/product/mb/#/?sk=Archive&kw=neo3 I got to know all Neo3 support PCI Express Generation2.0 or earlier. A new graphic board I'd choose requires PCIe 3.0. I looked up the internet for technical differences and found that there are problems existing with older mainbords. But nothing to be sure like: "there can be problems with that".
I'd like to get a HD 7770 running on my old mainboard. Anybody tried something equal or has experience/knowledge to help me with that? I saw in an entry a member of a technical forum that his configuration runs a sapphire HD 7870 on an P45 Neo 3 (see here: http://www.computerbase.de/forum/member.php?u=389051 )
Thank you for any help and good advices
