the one i saw last night was 4ghz which is easy on water and many people recon possible on air, will dig around some more as 3dmark isn`t the most reliable place to see whats happening.
I know hey can do 3.8 easy on air and have seen benchies of 3.9 on air too. its nice to see some competition back, no doubt with newer bioses and finer tweaking Im sure 4ghz on air isnt out of the question with them.
Im going to do some research on motherboards so i am armed pending loan extension :o)

Basically, the Gigabyte MA790-DS4H seems to be by far the best board of the bunch.

To get to 4Ghz seems to take around 1.50-1.55V, which for a 45nm is suicidal, but ignoring that, the heat output of the Phenom II is marginally higher than a Core 2 Quad, so you will need a tower heatsink with a high speed fan, and you will be getting temperatures hovering very close to the maximum at that speed, probably in the high 60s during a stress test.

Has the Phenom II price drop appeared in the US yet? Only one UK store seems to have done it so far.
Also, HD4830CF doesn't come close to an HD4870X2 at high res. Did you mean lower resolutions?
Sam,
The price just went down today. Was $275, now is $235! I've seen a number of 21-22,000 3DMark 06 scores at 3.8GHz with the HD4870x2 using the new Phenom II. Since 3.7 to 3.8GHz is pretty easy with the right MB, that speed range seems reasonable to me!

You are absolutely right about the MA790GX-DS4H being the best MB of the bunch, by a wide margin, Biostar has managed 4GHz on air with less than the maximum 1.50v of the Phenom II, but still doesn't perform as well as the DS4H, nor run as cool. I also see very wide differences in temps at those speeds. Folks that know what they are doing seem to have no problem on the DS4H running in the low 30C range at 3.8gHz. If you have decent case airflow, 3.8GHz is do-able with the stock Heat Pipe cooler without excessively high temps.
With the AM2+ 7750BE I'll be starting out with, 3.7 to 3.8GHz seems to be a snap, and you can overclock it to about 3.3 to 3.4GHz with just the multiplier, without touching the voltage at all. I'll be placing my order around the 30th, so I should have everything by the first week of February, and I'll let everyone know how it all goes. Here's my order, all made out!
$520 including tax and shipping. I'm Looking forward to it! I already have the 250GB Deskstar and the 80MM Silverstone fan. The 92mm one I'm ordering is for the HDD bay. I just want some forced intake air cooling over the HDD. I just this minute decided to use the fixed rpm 36.85 CFM Silverstone since it's cfm is more than good enough for the intake, so that drops the total price to $512. If I add a second burner, it takes the total price up to $542. My goal was under $550 delivered, so I'm right there, and can still get my Sceptre fixed! Sweet!
EDITED: To revise changes in my order.
Best Regards,
Russ

Out of interest, is the only difference between the DS4 and DS4H the HDMI, or does the DS4 have less overclocking ability?

Aside from the HDMI port, the DS4 lacks the better heatpipe chipset and VRM cooling and the SidePort memory for the OB video. From what I've seen, they both seem to overclock about the same. Since I'm not going to be using a video card, the DS4H is the best route for me to take!

Are you sure it overclocks as well with the onboard video enabled? Onboard graphics always used to be disastrous for overclocking in the past.

have some geil black dragon 6400 which i will loosen the timings to get it to 1066.
not too bad an upgrade :) novatech seem to have the phenom II 940BE the cheapest in the uk from what i can find at the moment. even if i find it cheaper I can walk to novatech from here so saves £ on postage :o)

overclocking headroom, plus to allow for another 4830, plus its cheaper than the Hx 620 at novatech lol
Want to keep the my 520 in current comp so i can play over lan when my mates up. dont really think it would be upto the newer system.
even if the hx 520 would run it it would still come to £347.27

Headroom? It's cheaper than the HX620 because it's not modular, but really, a VX550 would have done. I use an overclocked quad core and an HD4870X2 on an HX520, and it doesn't even get noisy, let alone stressed. This is because despite these components (and 3 HDDs) my PC only uses 400W under full load, plenty of headroom before the limit of 520, realistically about 560.

just went through it on extreme powersuply calculator with phenom at 3.9 allowing for 1.4 (1.5 is the max recommended for the chip) the 2 gfx cards 2 hd's dvd writer it comes out as 510w recommended psu
so maybe a 620 psu is more suited if i allow for full 1.5 @ 4 ghz it recommends 521w psu
Not that i would ever pump that much through it lol 3.8 is probably where I would stay, but if I get hooked tweaking the 1.5v vcore is possible lol, looks like water cooling if i get to that point though lol

The extreme PSU calculator is very over-zealous. I'm pretty sure I'm meant to have an 800W PSU according to that. Unfortunately the only accurate test I've found is to compare real world results and take some tests of your own.

It does allow for everything at once being utilised to about 95% So it would be a very rare day if that happened. But its a safe starting point to work back from :)
However if I manage to get the full loan im asking for 2 4870x2's could come into the equation plus a 26"+ monitor lol
got to allow for my tat to get finished as well and thats around 500 to complete my back :o|

And well beyond. Everything at 100% wouldn't generate anywhere near that much power.
Only a 26" monitor for two 4870X2s? Shameful, you can only get 2560x1600 on a 30" :)
In all seriousness though, don't buy two 4870X2s, Quad crossfire only scales in about 2 games, and it's unnecessary for the vast majority of them.
On top of this, two 4870X2s won't fit in most boards without water cooling, as the stock coolers conflict with a lot of southbridge coolers.

I put 26" + as could be bigger, it all depends on funds left over have to book the tat first, cos im not having my back heal in the summer lol itchy itchy.
GA-MA790X-DS4 looks like it could cope with 2 4870x2's as I wont really need any other cards in the system. but I get your point, might be worth sticking to 2 4830's for now, next gen cards will be here by the end of the year so might be worth holding some funds back incase.
Anyway I better call it a night, I can feel my better half's eyes burning into the back of my neck lol Night all

Night then!
Two 4830s will be more than enough for you, especially if you get something other than a 30" PC monitor. If you're not super rich, quad graphics is the first thing to cross off the list.

Sam,
Quite sure! A lot of the initial tests shown from various sites used the OBG when testing. Some were also done with Hybrid CrossFire as well. It didn't seem to cause problems AMD specifically says that since the video speed can be set independent of and separate from the overclock, it's no problem!

Sam lots of boards can take 2 stock 4870 x2s. Even some m-atx ones (looks at dfi).
If you are going down the dual x2 route, they will need a hell of alot of CPU power (i7) but as Sam says 2 x2s arnt work it, IMO I'd take 2/3 gtx285/260 respectively.

Shaff: Why, have you tried? I would have thought mine could, but real life told me otherwise.
Three GTX280s or 285s would be a better plan than two X2s as the performance still stacks (two GTX280s would be a waste of time, hardly any better than an X2 anyway, and three GTX260s is pointless, they're lack of memory means they still fall flat on their face at 2560x1600), but for SLI, you need i7. No way in hell I'd ever recommend an nforce.

I have had my x2 in top and bottom slot no problems. The grx295 beats the x2 in most games so why wouldn't Sli gtx 285s?
I have yet to hear a bad thing about the 780a chipset, and soon to be released is a new 980a chipset. Asus have presented their boards for it, and iicr so did gigabyte.

The Maximus II formula isn't most motherboards. Very few boards use that chipset heatsink design.
Also, the reason why you wouldn't use two GTX285s is because they cost £650. For 30% better performance than a £340 HD4870X2. Even rich people have limits.
The 780a chipset is relatively new, and we didn't think the 780is were bad when they first came out, why take the risk? AMD and Intel's chipsets are superfluous.

umm 780i was 680i..... the 780a has been out a while.
and yes, most people that will get dual X2s will get brilliant boards. and im sure the good board makers arent dumb enough to make boards that can support 2 or 3 of the top gfx cards.
the thing is he wanted 2 4870x2s, and 2 gtx 285s cost less than that. i didnt say get 2 gtx285s over a 4870x2. that would be stupid!

780i was 680i? I don't follow, sorry.
Neither the X38-DS4 or X48-DS4 can support two HD4870X2s as they use the same chipset, I'm not sure it's something every board manufacturer considers.
I'll be honest, if he wanted two HD4870X2s, he'd be better off getting two GTX295s instead. More expensive but there's far more value per pound/dollar/whatever than two GTX285s.
All things considered however, unless he uses 2560x1600 none of these choices are remotely realistic. One HD4870X2 is ample for 1920x1200.
