I tried to pick the best high quality yet bang for buck parts. It's a balanced build overall, with a focus on gaming performance obviously, plus the bonus SSD. Only pick the OC build if you intend to OC properly right away, the 1000 kr difference means it's not going to be remotely worth it unless you do.
Mobo Asus P8H77-V 829 kr (no OC) or
Gigabyte Z77X-D3H 1095 kr (OC)
CPU i5-3470 1575 kr (no OC) or
i5-3570K 1879 kr (OC)
Cooling Stock (no OC) or
Hyper 212 Evo 365 kr (though 212 is quieter than stock, can get it for i5-3470 as well)
RAM Crucial 2x4GB 1600MHz 429 kr
GPU Asus GTX 670 3495 kr (best 670 in town)
SSD Crucial M4 128GB 875 kr
HDD Seagate 2TB 7200RPM 949 kr
ODD Samsung DVD burner 169 kr or
PSU XFX 550W 645 kr
Case Fractal Design Arc Midi 799 kr (decent cooling from 3x140mm fans, includes a fan controller for quietness)
= 9934 kr (no OC) or 10869 kr (OC)
Also, you can add
Asus Xonar DG 249kr if you have good headphones.
Spending more would mean less bang for buck:
- Mobo - most likely the above are more than fine
- You're gaming so there's no point going above i5
- More expensive coolers are for heavy overclocking or super quiet operation (212 is very quiet at idle)
- Faster RAM has no noticeable effect on performance outside of benchmarking
- GTX680 would not perform more than 5-10% better for an additional 25% more cost. Upcoming GTX 660 also possible but underbudgeted
- 256GB SSD is simply not needed... well, 128gb will fill up from games pretty fast but loading times are still very good on a modern 7200rpm drive, it's not an issue
- The PSU is very reliable, anything more expensive would be either overkill in terms of wattage, or marginally more energy efficient, or modular (not needed on a 550W unit)
- Diminishing returns from a more expensive case
Thus, I don't think you should spend more now. Save the ~2000 kr leftover on future upgrades instead.
