The pooch :
So I found it's an insperion 660 so it only has 220w of power so it's a no go
I suppose you could always include a psu upgrade in the deal.
Still, a GTX750ti will run on pcie slot power only, drawing a max of 75w.
That is probably about the right amount of graphics power that the cpu can keep busy.
Buy an EVGA gtx750ti (no 6 pin ), Register it promptly, and see how things go.
If the cpu holds up and more graphics is warranted, then use the EVGA 90 day free trade up program(read the small print on their web site) to get a better card and upgrade the psu.
