AMD 3700+ => 64 X2 4600+ questions

[Rigsta]

Hey all, 2 quick questions:

1: Is it worth the 175 quid? This PC is primarily used for gaming, and currently has a x64 3700+ fitted. If no, any other suggestions for socket 939?
2: Is the 64 X2 compatible with any socket 939 mobo? Specifically the DFI LAN Party............

I forgot the model of my mobo, I'm gonna have to dig out the manual to find out >_> It was DFI's first ATI crossfire board if I remember rightly.

I am not looking for a complete upgrade here - would prefer to keep the mobo untouched since the high-spec ones are a bit pricey to go swapping every time I want a new CPU

Thanks for the replies everyone, I actually have CPU-Z but forgot I had it

Since I'm at work I can't view online stores atm, but has anyone found the 4600+ for less than £175? I understand you can't post names on the forums due to competitor rules, but just knowing what prices are out there would be useful cheers
