Building my first PC (Gaming Use)

Hi

 

I have been wanting to build a pc for a long time and have finally been able to get the money to build it. Could someone please have a look at the parts i have chosen and give me some feedback please?

Thank you in advance,

For cost vs. performance, a rough number for your budget would be most helpful. Plus parts that are mandatory vs. parts you can get along without for time being.

Looks good overall to me. Are the published read/write speeds legit on that SSD?

Wouldn't it be worthwhile to switch to 2x4GB RAM sticks?

Woops, yeah.  Link changed.
