if you get a unlucky his iceqx2 expect to still overclock stable to 1150 if you get lucky, they can go past 1300(wtf I know its crazy) I would say expect 1200-1250
for the cpu I would overclock from 4.2-4.3 to keep it stable but also to prolong the lifespan, it wont last as long keeping at 4.6, keep that in mind, I made the build to last
Also I used a great thermalpaste that will help lower the temperature and combined with the asus motherboard will allow you to reach 4.2 stable(at that speed it doesnt matter going higher since it wont bottleneck the 7950[basically 7970ghz] and it will prolong the cpu's lifespan keeping it at 4.2
the dual channel 1866 ram will beat single channel 1600 and corsair has great customer service
to me you can use any kind of hdd from a spare computer, but 250gb will be plenty and will give you a chance to wait a few weeks before giving up lunch for a week to afford an ssd or larger hard drive
the xfx psu is probably going to be a rebranded seasonic and I highly reccomend you get that over a corsair(psu are meh besides their ax series, since there are much better psu at their price when it comes to corsair) also if I am not mistaken the xfx is a higher tier psu than the corsair builder
please keep in mind the parts I picked are for not only the best $800 build (I went to $799), but also for the longest lasting build.
I did not use the 6350 because the 6300 when overclocked is the same thing but cheaper and allows more money to be put into other parts
the asus motherboard was chisen for better overclocking ability, much better customer service than msi, and their boards are evidently physically stronger than competitors. For $900
If you are building a new pc and thats what this contest is about, I would just buy the his 7950iceqx2 and keep everything and wait until the next gen amd am3+ cpus come out
I am extremely confident I won this not to brag.
