Hi, I am a long time user of the outdated Audigy 2 Platinum eX - which has served me so very well tbh. (I never even acknowledged the EXISTENCE of other soundcard manufacturers) however after a short spell on vista, and a useless attempt with creatives alchemy, back to XP I went due to abismal audio (positional audio) Anyway that was a while ago, and now, I am on WINDOWS 7 ULTIMATE (nice!) BUT HERE WE ARE AGAIN! CRAP SOUND. I decided to have a sniff about and what did i find.. THE ASUS XONAR! "With the introduction of Windows Vista, the whole audio architecture landscape has been changed. " "to provide full support for surround sound and hardware accelerated features by translating DirectX to the DS3D GX. While other solutions like OpenAL requires special installation and game support, DS3D GX doesn't. Gamers can enjoy DirectX gaming with hardware enhanced surround sound and EAX effects automatically and immediately after installation." omg... I WANT IT, NOW! lol ok, here is the thing, my ONLY interest is GAMING, positional audio, sound quality, EAX etc. So I do not want to spend twice as much on the DX if the DS would be fine, both the DS and DX have the same AV200 HD audio processor. FOR EXAMPLE - "Although the AV200 traditionally supports both Dolby Digital Live and DTS Interactive capabilities, in the case of the Xonar DS only DTS encoding support is offered" how can I put this, I dont give a...edited by mod. so what I really want is perhaps some clever ppl with experience of these soundcards who could maybe tell me if I would be losing anything relevent (to me) by choosing the DS instead of the DX, on account of its all tech gobble-de-gook to me. Oh the DS is PCI and the DX is PCI-E I dunno if that makes any difference, I will be happy to go for the DX if its worth it, I just want to be sure it IS worth it, for ME! THANKS very much in advance any advice rly will be appreciated. OH one other thing to think about, what with the DS being ENTRY LEVEL, and my soundcard, although old, was HIGH END, would the sound quality be better or worse?
