Help please! Will this work?

[Gelly54]

Hi all I'm looking to upgrade my system and have been doing my research for a few weeks now and think I have come to a decision.

Before I order I wanted to check with some more knowledgeable people that it will all work with my current mother board.

Im currently running the following:
Motherboard --- Gigabyte GA-M68MT-S2 (AM3+) MicroATX
CPU ---- AMD Athlon II X3 Tri Core 455 3.30GHz (Socket AM3)
GPU -----OcUK HD 6850 1024MB GDDR5 PCI-Express
PSU ----- Cooler Master GX 450W '80 Plus Bronze'


I want to upgrade the graphics card and the processor to the following:

Gigabyte ATi Radeon HD 7950 Windforce 3X 3072MB GDDR5 PCI-Express
AMD Piledriver FX-6 Six Core 6300 Black Edition 3.50GHz (Socket AM3+)

Im presuming that I will need to upgrade the PSU?
Would I be able to slot these items straight into my rig no problems?
Would I need to update the bios?

Sorry for all the questions, just really want to be sure before I make the order.

Many Thanks

Thanks for the reply.
The PSU is 13 months old.
As for the socket, the research I had done did suggest it was AM3 only but the description on my invoice did say AM3+!
So Intel something I hadnt thought of, so would your suggestion be better for games such as Arma 3/Bio shock than upgrading to Piledriver FX-6 Six Core 6300 Black Edition 3.50GHz?
Again Thankyou for your help and advice
