I didnt have any problem when i ordered my ramapge IV extreme

btw dude don't add an AMD ram to an INTEL PC :P its a mix cpu hahaha
just get the samsung green rams or get dominators you can water cool them later :P

the power supply i suggest you buy from here or the weight will be alot and they will charge you almost the same
and you should get a small SSD which i suggest should be atleast 256GB for primary partition then get a normal 1TB or anything cheap one for using

GPU i would say go for the latest :) 780 classified is coming up
