Mechans pretty much nailed it - find the speakers you prefer 1st. Then get an amp that is suitable for those speakers. Then you need to find sources for your media. $5,000 will allow you to assemble a *very* nice system. Expect to spend about 1/2 your budget on the speakers. Then about 30% ($1500) on the amp and about 20% ($1,000) on source and cabling. Keep in mind that these figures are not set in stone, be flexible, but not ridiculously so.
Do NOT spend a bunch on cabling, maybe $200 - $400. And then feed your system the best source material you can find. If you do all this, you should be quite happy...
