Solved Rebuild CPU and motherboard options

Specs: Windows XP Home Edition, Athlon II X4 640
Having sorted out my parents' rebuild, I can now focus on my own.

I would ideally like to have a full speed Crossfire board - i.e. 2 PCI-Ex16 so that in the future I can upgrade to a Crossfire setup. Having browsed around, I've come up with the following motherboards:

Asrock 990FX Extreme3
Gigabyte GA-990FXA-UD3
Biostar TA990FXE

I reckon that any of these should be OK, but the Biostar only seems to have a 4+1 power regulator.

As far as CPUs are concerned, I'm trying to decide between four:
Phenom II x4 965 Black Edition

I can get a Phenom II x4 965 for under £80 and I know it's a good processor but what I don't know is how it compares to the new Piledriver FX series chips, in particular the fx-6300 which is what I've just put in my folks' machine.

Any advice/suggestions would be useful and very appreciated.

Thanks in advance

Thanks for the link!

It would seem that it's pretty much a choice between either the FX-4300 or the FX-6300 if I stick with AMD - at least according to those benchmarks. If I can get it cheaply enough though, the i3 2120 seems to be a good bet. At the end of the day, the difference between the AMD Vishera cores and the i3 2120 isn't actually that big overall. If the i3 is too expensive, I'll probably go with either the FX-4300 or 4350.

As far as motherboards go, I'll go with whatever seems to get the best reviews on a decent budget, even if it's a little bit more expensive.

OK, I'm going to go with the FX-6300, so at least that's sorted.

Having read about the perils of trying to crossfire two Radeon HD 7770s, I'm going to go for a single HD 7850 or equivalent instead.

I'm still looking at getting a motherboard capable of decent Crossfire/SLi support so that down the line I can add a second graphics card if I want to. In that respect, I reckon I need a 990FX chipset, so the obvious options are:

Gigabyte GA-99FX-UD5 or the Asus Sabertooth 990FX R2.0

I'm aware that both boards are probably overkill at this stage, but they would give me a lot of upgrade options for the future including the option of getting any AM3+ CPU and going down the Crossfire/SLi route

Does anyone have a preference towards either motherboard/brand? In the future I may decent to OC the system slightly so is one board more stable than the other?
