With around 1100€ to spend you can do far better imo.
> Screen
- HD (anything less nowadays is pointless)
- okay specs, nothing special
> Mouse
- My fav budget mouse
> Speakers, headphones, keyboard etc.
- get anything cheap from a local store
> Dust filter
lolwat? Most cases come with a filter of a sort, it's pointless wasting money for extra shit. Just clean out your PC every now and then
> PSU
LC Power is a great budget PSU brand, though I opted for this one just because it was the first search result. Since LC Power is most likely cheaper, get it. You might want to look at a modular PSU if you want better cable management (this one isn't, but I'm too lazy to find one myself - you can google yourself).
> Network card
Fuck that, use the integrated one
> Rubber padding
lolwat[2]? Screw that.
> Case
Fuck CM, Core 3000 is my love for med towers.
> RAM
A bit better than what you picked, 1600MHz CL9 is the sweet price/performance spot imo
> CPU cooling
I personally prefer either a Noctua NH-D14, Prolimatech's Mega Shadow or Megahalems with some fast fans (Kaze Jyunis are cheap and have great airflow), or a Tuniq Tower 120. LC-based solutions from Corsair are pretty cool too, such as the H100.
> CPU
Intel. You've got the money, go for it.
> HDD
Fuck power saving HDDs, go for something with performance. WD Caviar Black / Samsung Spinpoint F3 are my recommendations.
> GFX
No way will you buy anything less than a 6950 2GB for that kinda money. No way. You could even do better, but I don't really see the point in getting anything stronger right now. Oh and unlock it to the 6970.
> Sound card
Unless you really need the sound amped or you're an audiophile, stick with integrated sound. Otherwise Sonar Essence STX.
> DVD drive
You don't need it. Trust me.
> Mobo
Asrock's Extreme3 / Extreme4 boards are always a cheap way to get lots of good features.
Price for this stuff would probably come in the 1100 euro zone, depends where you get them. Prices listed are from mylemon.at, though you can get a better deal elsewhere (I just really love mylemon because the cart is displayed so nicely :3). The unlocked 6950 should perform pretty much as a 6970, so check benchmarks if you want a realistic view on performance. Needless to say you can expect to be playing most games on high quality and a HD resolution, though some more demanding titles might require you to lower the res a bit or lower the quality a bit if you want a constant 60+ fps.
