Ewww. According to http://www.cpu-world.com/benchmarks/...5W,_BE%29.html you're just not gonna be happy with that CPU, period. Especially considering the upgrades to most of the game engines of late. Further research shows the core tech in that CPU is circa 2003, meaning I can't imagine how you're gonna multibox modern (or even not-so-modern) games, 5-boxed. Your best bet is dropping the resolution down to 1280x1024 or less, turning the DirectX options from DX11 back to DX9 if available, and reducing all the graphics options in the game.
