Macs interact with PC's much better than they used to. But, since they all change fairly often, I think you'd be best off talking to a dealer who sells both (and software for both). S/he can tell you all about the traps & pitfalls of the latest upgrades.
There are cards to slot into your computer which allow a PC to run Mac software too - cost not too onerous.
