I have recently upgraded my rig from a Q6600 (w/ 5570) to a i5 3570k (OC 4.2), MSI Z77A GD55 and a 6870. Sufficed to say my games (Skyrim, ME3, TF2) run a lot better but it seems I have taken a step down on the sound front (its just a bit flat, too quiet, no punch in games and dull in music).
My old system used a PCI X-Fi Gamer card (a fairly cheap thing < £50) but since the new board has no PCI slots just PCI-E I thought I would just use the on-board audio. My thinking here way it has been about 6 years since I last used on-board sound (my old mb was P965) so no doubt on-board cards will be perfectly adequate by now (perhaps even better than my 5yr old X-Fi Gamer). Alas, I was wrong, the on-board sound is about as good as it was in 2000 so can someone suggest a good PCI-E sound card ~£50 that you have experience with. The Asus Sonar DX and X-Fi seem to be the most common but there is also a Recon3D from creative but the only reviews I find are for a Fatal1ty version which i am not interested in, any suggestions? It is mainly for games but I do use occasionally for music and movies too.
