It is kinda contradictory to ask for i5 / dual video card setup and low budget at the same time ^^!
GIGABYTE GA-P55M-UD4
@139.99 does SLI/CF at 8x+8x, but it is unlikely you will get two video cards that tops that. It is a mini board tho, for low costs right?
Intel Core i5-750 2.66GHz
@ 200.00
get any ram you want, higher rate ones if you plan to overclock
wiinippongamer is right that, at the $200 CPU range (for i5), AMD is a better choice.
Of course, you will need to clarify what you are using the PC for the the best trade-off.
