Dual graphics on an a10-5800k or just buy a new graphics card

[pizzahead911]

So I just bought a budget "casual gaming PC" and I used an a10 cpu because I figure I can just spend $10 more for a cpu that it basically an old amd athlon quad core and get a GPU with it that I can use for a while. I was wondering if in the future should I go with dual graphics on the 7660d or just use a single graphics card that doesn't use too much power like the 750 ti, as I only got a 430 watt power supply. I plan to use the iGPU for at least a year or so but in the future I was just wondering which would be the better deal.

I would just purchase a new graphics card like a 750Ti.
