So I am some what of a noob when it comes to hardware but I have changed out a graphics card before. I don't do a lot of gaming but with my work I use a lot of screen real estate. I was given a 21 inch monitor (my other two are 21 inch monitors) for free because someone did not need it anymore and would like to add it to my computer. I tried hooking it up to my current HD 5570 but it does not allow me to use more than 2 out of the 3 ports at a time. I basically figured out that I will need to invest quite a bit of money in order to get one that allows lots of monitors in the future so I opted for two cheap Graphics Cards. Fry's in my area had an awesome deal and I picked up two:

New Graphics Cards - Diamond Radeon R7 240

Here is my Motherboard: http://www.findlaptopdriver.com/pegatron-corporation-2a86-mainboard-1-04-specs/

Also, since I don't do a lot of gaming do I need a new power supply? Right now I just have 460 watt

Let me know if you need any other information. I am just wondering if this is going to work? If it is...then do I need anything else to connect the two or are they just going to work when I put them in? Any help would be greatly appreciated.
