rams fine but pretty week, go for a 1333Mhz DDR3 if your motherboard allows it
processors fine tbh, it's intel core i7, that's like as great as mine if it had higher speed.
HDD is fine, don't bother with SSD.
could use a huge boost in video card, but not entirely necessary. heres mine

edit: oh, crysis doesn't have directX 9? That's actually very strange, in that case I'd suggest just getting a video card supporting directX11. Not rare at all these days.
