and wworked with l4d for less than 10 min(like 7-8 min) without a hiccup

now can any1 tell me wether i shld oc more or just settle for this?

That is a pretty good overclock. You might just wanna stop there, unless you feel like there is more room.

If you get any artifacts/"weird stuff" just lower the clocks and keep it there.

EDIT: Also, in the future try to make the spelling at least, a bit more careful! :p

I would take the Core down to 700 if i was you as 750+ is abit to high for long entensive gaming.

shader at 1512 seems fine :)

memory @ 1152 should be around 1250 Max as ddr3 can be oc'ed realy nice if you have fan runing at 80 :) dont go over that though 1250 as its max it will go, If you can push volts up on memmory on card you could overclock it more to over 1300+.
