First of all my PC's motherboard is Intel D845PESV and my speakers are Creative Labs Cambridge SoundWorks PC Speaker System.I don't have any soundcard.I use the onboard soundcard of Intel D845PESV motherboard.I will upgrade my PC in a few months.I am thinking of getting Intel DG33FB motherboard.Intel DG33FB motherboard has onboard soundcard and supports High Definition Audio.My question is will the onboard soundcard of Intel DG33FB motherboard be better than soundcard's like Creative Sound Blaster X-Fi Extreme gamer,Creative Sound Blaster X-Fi Titanium,Creative Sound Blaster X-Fi Platinum,Creative Sound Blaster X-Fi Titanium Fatality Serires,Creative Sound Blaster X-Fi Platinum Fatality Serires etc or will be the same?Will my speakers be able to support the soundcard of Intel DG33FB motherboard and high definition audio?
