Without a doubt, avoid Creative. Buy Asus, M-Audio, HT Omega - anything but Creative. Your ears will thank you!
First of all, thank you for your reply!
I´ll take your advice and found 2 soundcards for about he same price as the selected Creative:
1. Asus Xonar DX
2. M-Audio Revolution 5.1
Which would you recomment?
Also as far as a cooler - unless you plan to overclock it you don't need that. Stock cooling (at least on everything I've seen previously - perhaps Core i7 is different) is very sufficient and good at keeping the processor cool. I'm using a stock cooler on my C2D E8400 and it has never come close to overheating or even spooling up.
I am planning on some overclocking and wil keep the Thermalright Ultra 120 EXtreme as cooler
But thanks for bringing it up!
Given what you're going for with your PC, I'd recommend a 300 GB Velociraptor and if that is not enough space a secondary drive (ranging around 500 GB or so). Doing a defrag on a 1 TB sounds like utter torture to me. Say goodbye to your PC for a few days...no matter though, the sound card is the biggest issue I can see.
I actually was thinking about getting a WD VelociRaptor Backplane Ready 300 GB, 10.000 Rpm Hard Drive for Windows and stuff.
And keep the Samsung SpinPoint F1 1 TB for storage
What speakers are you using or planning to buy? If surround gaming is important to you you need a good set of speakers and that's hard to come by in PC speakers. As far as that would go, I recommend only the Logitech Z-5500s or if you can find a set (probably used) get the Klipsch ProMedia Ultra 5.1.
I was thinking of his little brother, the Logitech G51
But if the Z-5500 is worth the extra money I will take it!
