UPDATED This is my first rig. Got back into PC gaming in summer of 2012 to play DayZ. Started with a FX-4100, Gigabyte 970 mobo and GTX 550ti then upgraded to an i5/GTX 660 setup through Microcenter. Microcenter is amazing. Just dropped in a GTX 770.
CPU: As previously mentioned, I started out with a FX-4100 and, while not the best, I absolutely loved that thing. Overclocked like a champ and did pretty well for the $89.99 I paid. However, it was lacking in ARMA and Planetside 2 and when Microcenter had a sale during Christmas '12 I cashed in on my replacement plan and upgraded to an i5/Z77 combo at no additional cost. Will look to upgrade later this summer to Broadwell.
Heatsink: Cheap, efficient air cooling. Will be looking to switch to watercooling at some point.
MOBO: Love the mobo. a Overclocker forum I started reading when I first started building recommended it and it's been great. Some people hate on ASRock, but I like their products. Plus they're owned by ASUS, but with a lower pricetag.
Memory: Bought these two sticks back when I upgraded to the i5. Really miss the cheap ram prices from Christmas '12. Unreal the prices you see now on equivalent specs.
SSD: Great investment. Samsung is the way to go, although people will say otherwise.
HDD: Storage drive. Nuff said.
GFX Card: I have to say, I bought my ASUS GTX 660 DirectCU II back in May for $179.99 and it was a great piece of hardware. I got good frames (60+) on all the games I play at 1080p with medium/high settings. Not to mention access to Shadowplay. The GTX 660 is a great entry level card. However, I have plans to switch to a steambox chassis when Broadwell comes out (looking at the Silverstone Raven RVZ01) and wanted a GPU with a blower design for a small form factor case. The GTX 770 with titan cooler does just that. The low price is due to me using a gift card from my boss.
Case: Love this case. Clean, simple, elegant design. Really like NZXT. Great customer service, too. E-mailed them to see if I could get some rubber grommets for cable management and they shipped me some for free.
Power Supply: When I first started building, I went with a Rosewill 800W power supply that was major overkill. Spent $89.99 on it. Realized later my mistake, sold it and got this semi-modular PSU off eBay for $58.
OS: Took advantage of a Microsoft promo bug last February. Took some getting used to, but I like Windows 8. The metro stuff is annoying, but I like the snappiness of it.
Display: I recently upgraded to an 1080p IPS display which I absolutely love. I thought long and hard about going with that ASUS 144hz monitor, but it uses a TN panel and just didn't find it worth the extra money. Read a few articles highly recommending IPS monitors and all I can say is wow. Coming from a 1440x900 monitor to this is amazing. Had to turn the brightness down, but amazing colors and quality. By far the best upgrade along with the SSD.
Thanks for taking a look at my build. Any and all feedback is welcome!
