Finally decided to retire my e8400 and join the sb party(a trip at microcenter sealed the deal for me). Original Rig:
e8400
8gb ddr2
4870
xigmatek h.d.t
tx750
6 hdd and 1 ssd
Upgrade list:
2600k (purchased)
G.Skill ripjaw 12800 8gb * 2 set (pending)
another ssd to raid those vertex 2 (both of them are the old batch

)
Asus P8z68-v Pro (pending)
corsair H50 that I got it cheap and never used it
I have never overclocked anything and with this CPU I don't think god of OC will forgive me if I leave it stock. I do plan on using this cpu for a while so I don't plan on going 4.4+, a minor increase will satisfy me. Some help or some place to read about do's and don't will be greatly appreciated!
My tx750 is about to hit 3rd year I was wondering if it can support the new setup provided I am minor OCing?
I still have some cash left, video card is next on my list. I have a 460gtx at my sis computer but I do not see any big improvement over my 4870. With my budget of ~250 should I expect any decent up?
I know I need another ssd to take advantage of the z68 but is it true that I can do that later without reformat as long as I install it in raid mode?
Thanks!
