I wouldn't expect this cheap card to be an upgrade over onboard audio on most modern motherboards. There's also plenty of gear with an okay SNR but comparatively poor SINAD (and ENOB as a result), FR, and or linearity issues and internal sound cards are hit or miss with drivers. I'd wager the SINAD for this card is probably sub 90dB given how other sound cards perform (we want a SINAD of ~98dB minimum since most audio files are 16bit/44.1kHz and 16-bits can get ~96dB of dynamic range without noise shaping. A SINAD of 98dB gives an ENOB of ~16-bits).
Gaming isn't some special audio workload either. Those DSP features (e.g. simulated surround sound) Creative provides aren't really useful since most modern games already have their own DSP engines for positional audio (pretty sure it's basically standard at this point).
24bit/192kHz is useless as well unless you do professional audio work and need the extra headroom 24 bits gives you or are recording audio with sounds between 22.05kHz-96 kHz (outside of our hearing range) which a sampling rate of 192kHz can capture but 44.1kHz can't.
Also whoever is in charge of marketing at Creative should maybe learn that ohms aren't a unit of power.

I'm guessing you have around $200 to spend since you said you were willing to shell out the money for a "high-end" sound card. I always recommend an external setup over a sound card because the well engineered external ones outperform similarly priced sound cards. They also usually use USB's UAC drivers which means they are essentially plug and play, saving you the headache of dealing with sound card drivers.
For $200, the usual recommendation is the Khadas Tone Board + JDS Labs Atom. The Khadas Tone Board doesn't come with a case though (it's an add-on board for a Raspberry Pi-like PC-on-a-board) so you might want to spend a little more to get a case for it or go for the Topping D30 which comes with a case, though it performs a bit worse (SINAD of 107dB compared to the Tone Board's 110 dB. It's insignificant honestly and you won't hear a difference). Both should use the UAC2 driver which comes with Windows 10 (but not 7. Not sure about 8).
