Ram doesn't add long-term storage memory.
I know some people swear by SSDs, but for a gaming rig I personally would go with a 7200RPM 500GB-ish hard drive and spend the money eslewhere.
59.99 WD Cavier Black 500GB
74.95 G.Skill Ripjaws X 8GB 1600MHz
. (Don't technically need 8GB for gaming)
173.99 XFX HD6850
Also, didn't look at all the parts, but on Newegg the RAM
I linked is 59.99 (20$ promo code) and free shipping, and you could upgrade the video card to an XFX HD6870
, 149.99 (with MiR) and free shipping.
