770 = Older but still good performance - very close to 790. Maybe not quite as good at overclocking and not a viable option for Crossifre.
780 = Same as above but with integrated graphics, so only a better option if you don't have a dedicated graphics card. If you do it's just a pointless source of heat really.
785 = Same as above but very slightly better and has DX 10.1 support.
790X = 790GX without the graphics. Decent at everything, best at not quite anything. Does Crossfire quite well and is a good enough overclocker.
790GX = Same as above but with some pretty beefy dedicated graphics. Still got nothing on a card though.
790FX = Best really - amazing overclocking and fastest possible crossfire.

my gigabyte gama 770td3 motherboard has good reviews, almost as good an overclocker as 790fx but at nearly half the price!as said above, dont bother with 780, 785 unless u dont intend to fit agraphics card. only downside, no crossfire
Only if you really must have SLI,otherwise steer clear.
Nforce boards on all platforms are inferior to Intel or Amd offerings.
I'm not sure I agree with that, from personaly experience I have found it quite handy having the optional onboard graphics as I tend to get bored of a GPU and want to sell it so simply switch to the IGP and remove and sell the old card. Without having an IGP I would need to keep a backup card of some kind. It's a small advantage but it works well for me. I'm not into gaming just at the moment therefore I don't own a GPU but the HD4200 is holding the fort until xmas!
As far as I know once you install a dedicated graphics card the IGP is disabled and therefore is not "a pointless source of heat" as it's not active!
I'm still getting up to speed with all the different AMD chipsets but I've not seen anything on the other chipsets that is different or worth a price premium over the 785G?
I'm not sure why anyone (apart from 7GHz+ benchers) would buy a 790FX chipset costing approx £125/£140 as for that same money you could buy an Intel P55/Core i5
If you got big money then AMD isn't what you should be buying, if your on a budget then £150 will bag you a super AMD processor and chipset!
I think the 785G is a wonderful bit of kit, been using it three weeks approx and its solid as a rock with features galore, best of all its affordable!

I've clocked using it but I'm not sure I'm clocking it as it has multipliers for everything, running the chip using a 250MHz HT ref.Clock and running the chip-NB at 2.5GHz.
Started by working out stock vCore, VID is 1.425 but has been folding for a week at 1.200 (1.168vActual), this chip scales like a dog though with 3.375GHz needing the full VID amount! . . .Still early days though and I'm a slow clocker!

Here's two nice ASUS AMD 785G motherboards . . .
I'm not 100% sure but I think 785G is a non crossfire chipset, maybe that's where 790GX/FX comes into play?
If someone has DDR2 then I'm not sure if upgrading to DDR3 is worth it? at least I've not seen any meaningful advantage with DDR3 on the AM3 platform, if someone already has DDR3 then may as well use it! . . . . Having faster memory will certainly speed up the IGP results as thats the Video RAM!
[edit] well that's the Video RAM on the DDR2 boards but not sure how it works with the DDR3 based boards as they have Sideport memory also?

ddr3 sideport memory on the ddr3 version, so 128mb dedicated ram on the board.
That much I understand, my query was what happens when the frame-buffer breaches the 128MB of sideport memory? . . I am guessing it then poaches the system memory? . . . therefore the faster the system memory the faster the graphics memory?
Not really come across a graphic memory system that has two layers of different speed memory before? . . its a bit like the AMD Phenom II's with their level 2 and level 3 caches!
I'm building a HTPC so this thread has been quite useful. Though one thing that is swaying me towards Intel ATM is the cost of second hand CPU's. There seems to be loads of core 2 duo/quads available but fewer AMD chips going. Is this also the case on the MM (with my current post count I don't have access)?
