This was 3rd build I've ever done. My first two were low budget but solid systems for their time, with the last being built about 2 years ago. I bought everything off Newegg (0% 12 months ftw) with the exception of the monitor, speakers and headset. These were bought a year or more back.
I spent a lot of time researching both PCPartPicker, Tomshardware as well reading tons of Newegg reviews before I came to my final choices. My plan is to build another new system in about a year so and this has to last me until then, and I think it'll do just fine in that department.
System Goal - I wanted something that can play every game close to or at max for the next year. I think this system will achieve that but time will only tell. I also wanted to play around with OCing, and this was a great entry into OCing for the first time. Getting a 4.5Ghz @1.28V with temps <80 on Prime 95 was really nice.
CPU - I wanted to jump into OCing and after reading price vs. performance the i5-3570K fit the perfect spot for me.
Mobo - Z75... I know. However, for $60 I couldn't pass up the deal. I do not plan on doing SLI or Crossfire so the PCI limit is irrelevant to me at this point. I got a 4.5Ghz OC out of this little beauty so quite happy on the choice!
CPU Cooler - Ok... So you'll see my pre-build pic has a corsair H60. This was a total waste of money and delayed my build. My stock temps on Prime 95 were 70+! Ugh. Did push/pull, articsilver, the works... What a waste of money. I didn't realize at the time that it was on par with a stock cooler. This was my one big mistake. So I ate the $20(RMA/Shipping) and bought an CM Evo. 100% Load no OC the Evo had me @50C... Yea, H60 can suck it.
HD - I wanted reliability and a good warranty with my SSD. Based on reviews and research the extra money for the Samsung pro is worth it I believe. I will eventually get a 1TB for storage but at this point I don't need it and I'm a minimalist with my space.
Graphics Card - This baby OC'd very nicely. 30% fan speed and I top out @80C. Super quiet, fast and at that price? Was a steal.
Case - This baby has been amazing to work with for the price. You cannot go wrong with 200R. Next build will be style and performance and I'll go for something more flashy then.
PSU - Ok, I know it's coming... "Get a better PSU, these caps suck!" You're probably right, and my whole system may burst into glorious flames burning me alive at my computer... However, based on tomshardware review, I feel good about my choice. (http://www.tomshardware.com/reviews/power-supply-review-80-plus-bronze,3587-12.html)
Mouse/KB - I love these two! My 3 year old logitch G15 and my 69x needed to go into retirement.
I included all my benchmarks post OCing. I had a blast doing this system and welcome any feedback, good or bad. Cheers!
