Reddit mentions of Sound Blaster Z - Soundkarte - 24-Bit

Thanks you for answering. Well that would be the cheap combo, but I also was thinking about going for the HD650 + a sound card instead of a DAC for emulated surround etc (overhall a better alternative ?).

This sound card in particular would fit my budget (Creative sound blaster Z > https://www.amazon.fr/Creative-Sound-Blaster-Performance-ProStudio/dp/B009RPQA2G) combo'd with the HD650

Would it be a good upgrade while staying in the style of music / comfort I like ? And is the Creative Sound Blaster Z gonna be too cheap of a sound card for the HD650 compared to a Creative ZxR or an Asus STX II ?

What do you think ?

Edit: Or and HD598 + Creative ZxR/Asus STX II for a better balance instead of HD650 + Creative Sound Blaster Z ?

Edit 2: Well I just found a really cheap DT 880 Pro... and will probably order this one https://www.amazon.fr/Beyerdynamic-Casque-Hi-Fi-880-32/dp/B000F2BLTM?th=1 , I guess I just need a better DAC than the fiio E10K for this one. What about a Schiit one? You'd recommend one in particular ?

Thanks to Intel's hyper threading technology the CPU is a eight core. You won't have any trouble video / audio editing.
You don't need an aftermarket CPU, but it is quieter and keeps the CPU cooler than the stock one.
A quality motherboard.
16GB RAM are plenty for audio / video creation.
SSD for OS and main programs.
HDD for media.
GTX 760 helps in video editing and can play any game at max settings atb1080p.
A silence optimized case.
A good power supply with more than enough headroom.
A cheap optical drive, because who uses those?
If you want the start menu back in WIN8, try Classic Shell or StartIsBack out.
I don't know about your audio gear, but if you need a sound card: Asus Xonar Essence STX, Creative Sound Blaster ZxR, Creative Labs Sound Blaster ZxR, CREATIVE Sound Blaster Z. You should definitely do more research on these cards.

Getting a Soundcard really seems like a good idea for you. If you play on a laptop, get an USB soundcard like the creative Creative Sound Blaster X-Fi Surround 5.1 Pro.
If you've got a full PC, then I'd recommend a PCIe soundcard like the Creative Sound Blaster Z.
I have owned both of these cards and in my experience they are worth the money and work really well. And they also got some really nice software (the Z a bit better than the USB one) with good noise and echo filters.

EDIT: looking for used ones is really worth it in my experience.

I hope I could help you :)
