thinking of upgrading

[hardc0re_tid]

im currently running as follows:

Asus Maximus Formula SE
Q6600 @ 3.8
4gb Geil 6400 ULL
768mb 8800gtx oc2

what would be a good upgrade, eg i was running an e6300, 2gb 6400 prior to the q6600, what would see leaps and bounds above my quad setup?

basically what im after is mobo, ram, gpu and cpu, all other bits are fine

what about a solid state OS drive and a new gpu?

whats on par with the 5850/70 cards nvidia flavoured?

the 3.8 oc is on air by the way, would water cooling be a good investment? ive got a u2 ufo case by the way
