Larry is a gamer and got a new video card that supports RayTracing. He put it in his computer but it's lagging terribly. On top of that, he's now getting "green sparkles" everywhere. Is his machine too old? Leo says it shouldn't be too old at all, it's likely just a bad card. Green artifacts are usually an indication of a bad video card, so Larry should send it back for a refund or replacement. The GTX 1070 is better matched to his computer anyway.
From the chatroom ... the power supply may be the problem as well. Also, test it on another computer with a different monitor and cable. He can also try running the benchmarks app that came with it and see if the artifacts occur.
