it is a Sound Blaster X-fi Titanium, and what would be a better card?
As much as I dont like Creative and especially the X-Fi that Titanium is supposed to be a good card. I dont agree that it is in every case. The problem is related to the use of nvidia chipsets and ESPECIALLY with SLI systems along side the X-Fi cards. From Creatives website:
"Very lengthy handling of Interrupt Service Routines (ISR) and Deferred Procedure Calls (DPC) by the graphics driver on nForce motherboards (Asus, MSI, and Gigabyte are some motherboard vendors that use this chipset), particularly when nVidia SLI graphics are used."
That said the Auzentech cards (also a X-Fi) dont seem to suffer with this problem and so rather than push the blame on nvidia I have to say that the blame lies with brand 'C' and somewhere within their drivers but I am not tech savy enough to say for sure but I know what works in my experience and that is what I am reporting to you. I decided to go with the HT Omega line and I have had very good success with the Striker 7.1 card even on Vista.
I dont want the burden of your upgrade on me though if it doesnt work for you. Please bear that in mind. I hope you can RMA that X-Fi.
