I was leaning towards 2 gtx 460s, as I read they are really good cards and best performance for the money.
I read your posts yesterday and you keep saying 2gb of ram so I'll buy them with 2 gb of ram now.

I was just about to build a powerhorse workstation with 2 6core xeons and stuff a month ago ...

so what's the benefit of having 2 cards instead of one, besides the dual monitor option?
Can't I use them both for rendering?
