Connecting a receiver to my PC.

[de8212]

I currently have a set of old logitech 560's connected to my PC. I've always watned to connect a receiver to my PC and get some decent speakers. Since I now have an extra receiver I am considering it.
The receiver is an onkyo 575x.
Speakers I am considering are Polk RM6750.

MOtherboard is in my sig and I'm having trouble pulling up gigabyte's website to get details on the on board sound/connections.

Would rear/center channel work in games? All I really play are COD:W@W.

I know it may be difficult to say, but would this be a significant upgrade?

I had the 560s for a few years and they were pretty decent by computer speaker standards. I ended up upgrading to a similarly priced speaker set from the 560s (they were full sized rather than those Polks though) and it left me wanting more so I ended up upgrading again within a year or two.

The Polks probably are better than the Logitechs, but I would recommend waiting until you could get a more significant upgrade. One option would be to take the upgrade in steps. The Logitech z-560 satellites are 8-ohms, so they would be compatible with your onkyo receiver. With an adapter, you should also be able to get the Logitech sub going with the onkyo's sub pre-out.

That would mean that you could use the 560's satellites for surrounds / rears, keep using the logitech sub (perhaps with a lower crossover point set with the onkyo), and then spend your budget on just three front speakers (the most important ones).

As for whether 5.1/7.1 would work with games, I haven't been keeping up with motherboards and onboard sound. Does that one have Dolby Digital Live or DTS Connect as a feature?
Actually, I just looked it up on the website and it does indeed list DTS Connect as a feature, so you should be able to get surround sound from games using a digital connection (which is the easiest way to do this).
