I've recently been gifted with some new parts and combined with some old parts from my now defunct PC, I'm hoping to assemble something that can play some of the more demanding games available on the market right now (Vindictus, TERA Online, Guild Wars 2)
To start with:
Motherboard: Asus P8Z77-V
CPU: Intel Core i7-3770K socket LGA1155
GPU: Asus GTX470 (Old parts)
RAM: 2x Corsair Dominator 3x 2gb kit (Old parts, will be using 2 sticks from each kit to get 8 gb of ram)
What I need advice on:
PSU (I have an old 550w Antec Truepower Trio, but not sure it will be enough)
HDD (Might opt for a SSD, depending on how much the first two cost me)
The 550W should work fine
With a case, honestly, get the cheapest thing you can find if your trying to save cash. Just make sure you have good airflow.
As for the hard drive, yeah SSD is really nice. I use a SSD as my main drive for the OS with a larger HDD for games and such.
Sounds like it should run fine. the GTX470 is still a viable video card.
