Hello - I have an XPS 630I with an AMD Radeon R9 270 video card. Some of the games i try to play are not working very well and i was wondering if a second video card would work better or if i need to upgrade my computer. What are the advantaged of running two video cards? I am trying to figure out where the bottleneck in my system is. Thanks so much for the help. The computer spec are below.
