Hey guys, I just ordered up a new Core i7 gaming rig. I didn't cut any corners so far and I don't want to start at the sound. I'm using the asus P6T V2 Motherboard. I'm not sure how well the on board sound is but I don't expect I'll get the full potential of a pair of high endish headsets from it. I'm currently looking at the Sennheiser PC 350's. I don't have any idea on which sound card will take full advantage of the headset. I'm open for suggestions and I'd like to keep the total bundle (headset and sound card) under 300. I will pay more but only if you highly recommend it from personal experience. On a side note, I plan on trying out windows 7 as money is quite tight at the moment and it is a free OS =/ (drivers and compatibility going to be an issue?) This is a purely gaming rig, classical music and heavy bass from R&B will have to tough it out. Thanks for your help!
