Re: simple question on my gaming rig
You putting a 750W in there will not harm a thing. You'll be perfectly fine. It will leave you for better upgrade ability in the future.
I use onboard audio. IMO, unless you're an audiophile, I see no real reason to have an aftermarket sound card. Then again, I have never had one, so I don't know the benefits/drawbacks.
