questions for graphics cards?

[NBSN]

I wish you gave a budget and more specs for your system. Without knowing the specifics of your particular system, I can't tell you what is best to do. Your system might bottleneck if you get one of these graphics cards and don't have the proper components such as a decent CPU. Your motherboard might not support SLI, or your case might not have enough room or be able to provide proper cooling for certain graphic card configurations. Your power supply might not support these cards or SLI setup. Much more information is needed. If you plan on getting three monitors, what resolution are you trying to set them at?

Wish I could give you some good information, but without knowing a lot more, the information I could give would possibly be worthless. You can message me at https://www.facebook.com/pages/NBSN/205302762950470
if you want to actually get some decent assistance.
