hmm... I have never been an AMD/ATI fanboy.
What is going on w/ TH2Go right now and Matrox in terms of support? It appeared to me that with the release of new nVidia drivers and TH2Go drivers that all windows 7 issues had been resolved? Maybe i misread or missed something.
I doubt i will go eyefinity - especially not after having just purchased a new GTX260.. i might have to wait a year.
I don't think it has anything to do with fanboyism. It comes down to a question of what works with what you want.
If you are going to go the 1050 route then TH2G would be good (but you would not, in my opinion be future proofing), but if you go with the 1200 monitors then by all means sell your gtx260 and get an eyefinity card. IF it is a cost issue then wait a bit and save up (like me, it has taken 3 months to finally get everything ready for my system) or not. Like I said it comes down to what you want.
