Approximate Purchase Date: this weekend for some of the parts at least
Budget Range: 600-800 (without monitor or graphics card)
System Usage from Most to Least Important: mostly for media PC (hooked up to my 50" TV), but I would like to be able to play games on it (Star Craft 2, CS: Global Offensive, Diablo 3)
Are you buying a monitor: No
Parts to Upgrade: Pretty much everything, my last build was 8+ years ago
Do you need to buy OS: Yes
Preferred Website(s) for Parts: newegg.com
Location: Boise, ID (USA)
SLI or Crossfire: Probably not, at least not in the near future
Your Monitor Resolution: 1920x1080 for my 50" HDTV
Additional Comments: quiet would be nice (it will be used a lot for Netflix, watching movies, etc), and also I am looking for it to be flexible and upgradeable in the future.
And Most Importantly, Why Are You Upgrading: I've been using my laptop, and it just can't handle the TV at really high resolution.
Need advice on what to get for MOBO and Power Supply. I'm leaning towards not getting a video card for now and picking one up for Christmas or Black Friday. It is only a couple months and from what I've seen the integrated graphics (HD 4000) can get me by until then.
I would recommend going with AMD vs. Intel on price/performance. You simply get ripped off with Intel. I strongly recommend the new AMD Trinity A10 processor for excellent GPU + CPU performance. For what you need (HPTC + light gaming) the AMD A10 Trinity APU is ideal.
CPU/GPU: AMD Trinity A10 5800K ($125 NewEgg). The HD7660 GPU performance is as good as dedicated cards (see Tom's Trinity reviews).
Mobo: ASRock FM2A75 Pro4 ($79 NewEgg): 2x PCIe, 5x SATA 6GB/sec, 6x USB 3.0, HDMI out, Realtek 8Ch HD audio, optical out. ASRock is making the best mobos these days. I've bought more than 10 different ASRock boards over the past 3 years now and never had to RMA one.
Power suppy: Rosewill CAPSTONE-450-M 80 Plus Gold PSU ($64.99 NewEgg). You simply can't find a better PSU for the money! The CAPSTONE series is an awesome value for 80 Plus Gold level performance and quality.
With this AMD build you'll save a hell of a lot of money vs. an Intel build and most likely get better performance (definitely better GPU performance vs. Intel) and you can avoid having to get a dedicated GPU.
