PS3 this week!!!

Hey everybody!

Payday for me is going to be this thursday and i will have enough money then for a ps3. The model i plan on buying is the 40 GB. The only question i have for you fellow gamers to anwer is what games to get. I have narrowed it down to: Uncharted, Warhawk, RFoM, Unreal Tournament. I excluded CoD 4 and other multi plats because i have a 360. I plan on getting two games with it and those are my choices so far, but feel free to give out your opinions! Also i was wondering if a headset is real necessary right away for online gaming? That would be part of the reason for me to get warhawk right away otherwise i would wait til my next check.

Thanks for all thehelp!
