I've been looking to upgrade my old rig for a while now but always wanted to think it over properly and see what is available (to prevent "lordservant scenario's" (though lulzworthy)) but against my better judgement I got caught in the moment and just bought one.
Asus P8Z77 mobo
i5 2500 3.3 GHz
4x 4GB ram
Sapphire HD 7950
650W power supply
and misc. stuff like windows 7, 120gb SSD
Total cost just over 1000 euros
I hope it is a non-terrible purchase
Anyway I've decided to try and assemble it myself. Never done anything of the sort so protips are welcome. The dude at the hardware shop already said to be especially careful with attaching the processor, since the warranty will be void if the pins get bent. Anything else I really need to know?
