How much the second card going to cost? What is your entire spec? If you have the money going for stronger single card will be much easier for you.
The second card is going to cost around $170, my specs are: AMD A8-5600k CPU,
Gigabyte AMD Radeon HD 7870 2 GB graphics card. 420 watt power supply, 8 gigs of RAM, and GA-F2A78M-D3H motherboard
