I play all of my games in a relatively smaller room (~11x11 feet) at a desk, and was previously using an Onkyo 2.1 HT system before it crapped out. Never really loved the sound, but it was a convenient AIO solution.
Earlier this year, I replaced them with a pair of Edifier R1280T near field bookshelf monitors:
They work really well for me since all of my consoles run to my TV, which I then output via the headphone jack to these. Same from my PC. The two inputs aren't discrete, so sounds from both sources can be heard at the same time. This actually works out pretty well, since I can just play music from my PC while playing anything on console, pause to watch a video without switching sources, etc.
They look nice enough, but more importantly, they sound really damn good IMO. I'm not an audiophile/expert, but grew up with speakers from Alesis, NHT, B&W/Solid, etc. and headphones from Sennheiser, AT, AKG, among others. For the money ($100 for the pair), I don't know if you can do much better. They've continued to sound even better and richer as they've broken in over the past few months too. I'm quite satisfied with them.
