P3d

Hey guys, I need your expert advice on what could be done to get smooth graphics on my computer? It stopped crashing after I added a second graphics card. So I did everything I can - overclock GPU/ recommended setting found on net. But lag is still there. Any advice is greatly appreciated. PC...

I'm Building my first PC right now and I don't know how to wire some things, or if I even have the correct cables. Is their a guide somewhere that can help? Thanks
