hi, im after a new sound card i dont no anything about them realy so after some advise ive been looking at Creative Sound Blaster Audigy 4 Pro 7.1 or the Creative Sound Blaster Audigy 2 ZS Platinum and now noticed the new adidgy X-Fi im looking for something that i can use as my home entertainment system and for my PC gaming, i was looking at the audidgy 4 pro 7.1 because i can also plug my guitar into it, apparently. Im gonna get the speakers with the sound card, not sure what there going to be either yet. my budget is going to be around £200 max. thankyou
