Processor upgrade (I'm an idiot)

[JimJam123]

My friend's looking to upgrade his processor after this forum basically said it's rubbish.

Specs are:

-4x Kingston 4GB 1333MHz DDR3 Non-ECC CL9 DIMM Memory
-Asus M5A78L-M/USB3 Motherboard (Socket AM3+, Up to 16GB DDR3, USB 3.0, uATX)
-Seagate ST31000524AS 3.5 inch Barracuda 1TB GB 7200rpm SATA Drive with 32MB Buffer
-Asus GeForce GTX660 TI-DC2-2GD5 Nvidia Graphics Card (2GB, GDDR5, HDMI, DVI-I, DVI-D, Display Port, OpenGL 4.2, DirectX 11, Nvidia 3D Vision Surround
-Corsair Gaming Series 2013 Edition GS 800W ATX/EPS 80 PLUS Bronze Power Supply Unit
-AMD Bulldozer FX-6100 Socket AM3+ 6 Core Processor - 3.30GHz, 3.90GHz Turbo
-Samsung 840 Series 120GB 2.5 inch SATA Solid State Drive

So from the above, what processor would you recommend?

I can see people are leaning towards intel, but if I was to stick with AMD what motherboard and processor would you guys recommend? Feel free to leave suggestions for switching to Intel as well.

Much appreciated.

Just saw your original thread, any reason you ignored all the advice ?

The original was me requesting a build for myself as my friend was going to give me his processor. Once he found out his processor wasn't great he wanted to upgrade it going by what you guys said, hence the second thread.

What`s the budget?

Probably about £350 for the motherboard and processor. Any other suggestions are welcome as well.
