Could someone please give me some advice on a speaker setup for my PC?

Hello, today I have a Creative GigaWorks S750 THX 7.1 Speaker System, which contains a pretty powerful punch for a PC audio system. However, is there any way I could get a more sound powerful for £ 200 - £ 300? I read that the use of loudspeakers hi-fi is a bad idea, because they contain magnets that can damage the PC hardware, if placed too close (But, obviously, a PC audio speaker set required to be set up close to the desktop. The alternative is to use only the music signal from the computer as a source in a system that is independent of and not in physical proximity to the computer. How do I configure it? How would incorporate an amplifier in the equation along with other suggestions? Consider the fact that I have a Fatal7ty Gamer XFI Platinum sound card.

All very well have a big system. Too large and you will blow your output transistors in the sound card. Suggest that if you want to shake the house down, put an amplifier between the PC and the speakers and let the amplifier do the job.
