oh holy cow an MMX unit, its like 1994 all over again.
any way a little late to this party but considering that the OP is going to use a existing videocard and then upgrade to a 750Ti that an APU would have made more sense and then swap that 750Ti with a similarly priced AMD card that would have the ability to make use of the onchip GPU and get a bit of a boost out of it?
I've got a 750Ti and its kinda got some weak balls compared to some at the same price or even a generation behind that would be the same price.
I mean an R7 260X is about the same price and, on paper, seems better than the 750Ti
