slightly slower but still powerful gpu for 1920x1080 gaming...the 7850 is the current 'sweet spot' gpu
better quality power supply, lower wattage, but with 28 amps on the 12v rail, plenty for this build, which will use about 300W assuming you maximize the fans
120 GB SSD at SATA III + 500 GB HDD at SATA II.
for fast boot, the SSD is so very, very worth it -- 15 seconds from power on to ready to use! Load times for WoW regions under 2 seconds.
fans CAN be daisy-chained off a molex as well (and what else will you be using molex for anyway?), and the 309W usage assumes you are using 7 120mm fans in the Challenger U3. (1 front, 1 bottom, 2 side, 2 top, 1 back)
the 3450 and SSD is a better bang-for buck than the 2500K and no SSD
Alright, thanks ScrewySqirl. He told me to ask if he should splurge and get the 2500k and Z77 so he can futureproof his build a bit? This has to last him quite awhile. (Intill he finishes four years of college) I said it was a good idea.
I'd love to save him some money, but I don't think a 3450 will last him 3-4 years. I might as well get him a GPU cooler too. He plays Skyrim and other games on his crappy budget laptop, so I think he'll be happy either way for the time being. Thanks ScrewySqril for the help.
