------------------------------------
As you can see, this is not a cost-optimized gaming machine. :P And a lot of the parts are more expensive than you can typically get away with, so I hope I'm not scaring any perspective builders/system buyers with these component costs.
An example being the power supply, kinda pricey at $130. But it is fully modular, gold-efficient, quiet and Seasonic-grade quality. :) I might still look at alternatives, though, so if anyone's got any recommendations that fit my quality and performance requirements, feel free to post!
Things I'm not sure about:
-It may be worth it to get the non-hyperthreaded (3550K) CPU instead. I'm not sure how useful HT is in applications that would benefit from more than 4 cores. There's a potential to save ~$100 here without much (?) performance loss. Something to look into!
-I wonder how much the NVIDIA 670 Ti will cost, and when it will be available? Right now, the AMD 7870 is a powerhouse for what you pay for--demolishes the NVIDIA 570, beats the 580 sometimes. But if the 670 Ti gets released at a similar price point and offers more performance, then it's worth considering. But NVIDIA can't really produce 680s right now, so I don't know the likelyhood of them releasing 670s any time soon...
-I want 16GB RAM in 2x8GB setup (for future potential 32GB upgradability!), with 1600MHz speed, CL9 timings. Not sure if Patriot is a trustworthy brand, though.. and selection for alternatives doesn't seem plentiful. u_u Kingston plox? Or maybe I'll get that Corsair with the stupid tall wannabe-heatsinks...
-I hardly ever use the optical disc drive these days, with games on Steam and all. Nonetheless, I'd like to have a half-defent DVD burner, maybe with Blu-Ray support. Dunno which brands are considered top grade in quality, however. LGs are typically "okay." I've heard Lite-On was nice, but idk... D: If someone here is an expert in optical drives, feel free to give input. Otherwise, I'll go research myself. :P
-That Sabertooth motherboard is nice, but I'm wondering if those mini-fans on it generate noticeable additional noise. If they do, I may get a simpler board. D: The main thing I like about it is that it's made with higher-quality parts than normal. An alternative would be Gigabyte's "ultra durable" boards, I guess? Z75 boards might be cheaper without losing too many features, too.
Still feeling kinda bad replacing my nicely-running 6 year old system. D: But my parents could really use, compared to my old P4 laptop that they're using as a desktop right now. :|
