Initially I thought that my new Radeon 5870 was faulty (see this thread for details) but after my PC refused to POST with either of my 8800 GTX's it seems the problem is more likely my motherboard. Being a Asus Striker Extreme it's basically impossible to find a new one so I'm left to scour eBay. They seem to be going for anywhere between £65 to £100 and I don't fancy paying that much right now. So I was wondering can I use any NF680i based motherboard as I basically don't want to have to re-install Windows. Unless of course that's not an issue anymore and you can swap motherboards without having to re-install Windows?
