hi everyone ..im kinda new here...im playing for a week now, and im enjoying the game...

so i want to play the game with setings max out and not have slow donws at 1080p res.

here is my rig:

I5 2500K 3.3 gHz
xfx hd6950 2 Gb
4 Gb corsair vengeance 1600mhz
500 Gb hd(no SSD)

what u guys think? does it worth to change my graphics card? or just overclocking my CPU to 5 Ghz and buying an SSD and one more clip of 4g ram is enough?
