Alright, but I want a good enough sound chip. A Gigabyte G1.Sniper B5 would be good?
I updated my config, poor amazon guys where about to deliver the other one when I changed it:
CPU: Intel Core i5-4570 3.2GHz Quad-Core Processor (EUR 164,97)
Motherboard: Gigabyte G1 Sniper B5 (EUR 98,84)
Memory: Kingston 8GB (2 x 4GB) DDR3-1600 Memory (EUR 69,49)
Storage: Samsung MZ-7TE120BW SSD 840 EVO BASIC 2,5" 120 Go SATA (EUR 84,52)
Video Card: Sapphire 11217-01-20G AMD R9 270X 1020 MHz 4096 PCI Express (EUR 195,55)
Case: Reusing old case (If cooling becomes a problem I could opt for a corsair 300r or 500r)
Power Supply: Reusing old power supply (a Corsair 550HX)
Total: 613€
Basically just 13€ more euros, except this time I have a 4GB graphic card and a much better mobo sound chip.
edit:
For my build I used a msi b85m p33, the only downside being that it only has a single pcie slot. Any b85 board that fits your case should do. Most boards have good enough sound these days, get asoundcard if it's really important for you
Damn! Well the difference is less than 20€, I'll keep it.
