An FX with a better GPU will do better in games than an i5 with a lesser GPU. If you can afford to go all out, of course go Intel. For a small budget like the OP has, you go with AMD and get the better graphics card. An FX 63xx or 83xx is not going to bottleneck any single card GPU. Maybe a tri sli or quad crossfire would have some issues, but this budget wouldn't allow for that anyway.
