Current system upgrade dilemna

[TheInfamous]

Hey guys,
My specs on my current pc are:
AMD Phenom II X2 550 Black Edition
Sapphire 512mb HD 4850
Gigabyte GA-MA770-UD3 770
Kingston 4GB (2x2GB) DDR2 800MHz/PC2-6400 HyperX Memory
Corsair 400W CX PSU

This setup has served me well but now I am being left behind, I was trying to play APB but it seems even on lowest settings and 800x600 resolution my fps was bad.

I have about ~£200 spare and I am thinking of buying a 955 since my mobo is an AM2+ socket and also I want to get a 5850 but the problem is will I have to buy a new PSU aswell?

Any input would be appreciated,
Thanks

I got 1x 500gb WD Black hard drive and a DVD drive that I don't even use plugged in

Would I be able to overclock with that PSU?

awesome, thanks for the help guys. Better than buying a whole new rig and I can sell the 550 and 4850 on fleabay for a nice bit.

Okay I have made my order now, thanks for the help. Will hopefully be playing APB in hd @ 60fps on Tuesday

Guys, will I need to reinstall my OS after upgrading the CPU?

 

[TheInfamous]
