Ah OEM. Normally not a problem for me. I was going to get an OEM but it is very difficult to get hold of the drivers for the OEM products online. There website doesn't list the OEM version under drivers downloads and their tech support said "You can buy a CD if you wish"
I've had Creative Cards before (PCI 512) which i bought with the speakers and it was good. However it causes BSOD and all sorts of weird problems on my A8N-SLi but works fine on the original PC it was bought for 5 years ago.
Really just wonder if it was an upgrade or a downgrade. Not really an audiophile, occasionally game but just want to free up the CPU from the Sound as i think it's causing some stuttering esp when I'm working and using my Freecom USB DVB-T TV Stick at the same time.
