To start off I've done a fair bit of research and some basic upgrades in the past, so there's still a lot I don't know. I'm in Australia so I can't really import anything from overseas sites like newegg, I'd prefer to use either: http://www.umart.com.au MSY
Based upon just umart I came up with a build I thought was build I thought was appropriate. However, although I think everything works, I just want to check (I mean just yesterday I thought I could couple an old video card with a new one in SLI...) I'd be using this for CAD modelling/gaming, preferably on the highest settings for current FPS games and skyrim +mods which I gave up on since my old pc still has a Pentium 4 on an 8 year old motherboard I think. It would also be nice if the system lasted a fairly long time before I'm forced to upgrade.
Just a note, I have access to windows 8 and a old dvd drive, I have no real use for a blu-ray one yet.
So my main questions are: Does it work? For my requirements, am I shooting too high? What should be downgraded/dropped? Any feedback about parts that have a bad history would also be great.
EDIT: I'd like to buy this by the start of December. I'd like to use SLI in the future and overclocking. I feel like I should also add that from the umart suplier this is a $1270 build at the moment, so keep any changes below $1150 on PCpartpicker.
