MSI 8800 gts oc questions???

I want to ask a few questions people about the MSI 8800 GTS OC edition...

Is 8800 GT better than this vid card cause I bought 8800 GTS OC and I feel like I made a wrong choice... I checked the prices in nvidia home site and GT is expensive than GTS... I live in Turkey and in here GT is cheaper than GTS... How is this possible

And second question is... Can I overclock this GTS more is the default cooler on it enough for more overclocking???

Thanks for all your help

112 SP 8800GTS (G92) > 8800GT > 8800GTS (G80)

if u have the old 8800GTS, then keep it!
Do u have any single problems with games ?
8800GT is better but when u can play every game @ good settings, then why change it ??

again if u have the old 8800GTS (G80 with 96 SP) then keep it , dont change it
