In the APU based ones you should change the RAM to high speed ones. the reason is the APU's dont have desidnated RAM and use system RAM so the high speeds will help alot if you decide to start gaming.
Some of the intel builds don't make too much sense considering you've implemented a 4770K and gone with a GTX 660, because a 4670K would be perfectly suitable for gaming, and the additional money saved could be invested in a better GPU. Not that the 660 is bad, but for a gaming oriented build in the above $800 mark.
Also, what was the purpose for these builds? Templates? Reference for incoming builders? I think I get the reason why it'd be helpful to have these, but I think treating builds a lot more uniquely is part of the purpose of custom PC's.
man those are good builds, I would change a few things slightly, for the amd $1000 one go with an asus M5A99X EVO motherboard, it's cheaper and will run fine, i have made a new $1000 build list that will run mad nuts
Never recommend this ssd Kingston SSDNow V200 it was a big fail for kingston and should of been discontued crappy firmware drives dieing for no reason chips overheating ect ect the kingston v-300 drives are better if your looking for a cheap ssd (i am useing one at the moment) but there hyperx drives are the ones to get if your looking for a kingston drive
