I am going to build a new system for gaming (games like Battlefield 3, Assasin's Creed, Crysis 2 etc.) and entertainment. I'm a bit confused when it comes to the psu purchase so I need a few recommendations on the wattage I'm going to need as well as the brand and so on. I would also use some help with the sound card. My dad likes listening to music (he wants quality). Our current PC has a Sound Blaster PCI card (an old one) but it really does its job. Unfortunately I can't use this card on my new system because I need it on the old one (we will still be using it) Should I buy a discrete card or will the onboard Realtek ALC887 8-Channel High Definition Audio CODEC do just as good as the Sound Blaster PCI? Do your best to inform me. Any other recommendations concerning the hardware is also welcome. If it's possible I would like to stick with the 800-850 € budget.
