Budget Gaming Build for CSGO

[KermitTheFrog]

I am looking for a budget build at around $500-600.
For a while I will mainly be playing CSGO and I am looking for a good build that I can just upgrade over time. I was thinking about getting an Intel i3 cpu with a Z97 motherboard and upgrade that over time if that might work. Any suggestions are welcome, but I am really leaning more towards Intel rather than AMD.
