What's the current best MB for AMD X2?

If you want a higher score Nvidia is the way to get there. But if you want an All-in-Wonder you have to sacrafice something.
The laptop I have on order will probably do better than your current score
(AMD X2 4800, Geforce 7800 GTX Go, 2 gigs ram)

Try Geforce 7800 GTX. You should reach around 7k in 3dmark 05.
I get just over 10k.
You might liquid cool if you are going to get into the benchmark game (OC'ing wills surely follow)
Nice PSU by teh way. My 850 is a monster. I have a 510 SLI in mothballs.

I'm running an Athlon X2 3800+ 2.0GHz Toledo core at 2.5GHz. I have the Asus A8N SLI Premium board with a BFG 7800GTX OC. I get about 8860 in 3DMark05.

If you want to overclock get a DFI board.

Nice computer but i would have spent more money on videocards instead of that expenise poo core proc.

I would highly recommend going with a DFI board!

Specs in sig. DFI LanParty NF4 Ultra works great and lots of support. All kind of o/c options, perhaps too many if you don't know what you are doing, but their forums are extremely helpful and full of guides and information.

THunDA has most of the useful guides listed in his sig.

My lappy is the Hyper FX7.
I have the Asus SLI board in my ALienware rig, thinking about switching it out for a DFI board.

It would be a good decision on your part. DFI's are the most configurable and stable boards considering how far you can push them. Great support too!

The only problem is if I change out the mobo I will probably replace my 6800 ultras with 7800 GTX 512s which also means I need to buy new waterblocks for them . . .

Ahh, the perils of upgrading...what's your cooling solution; water or tec?

I have an Alienware Aurora ALX SLI with a Koolance H20 system I modded with a thermalkake Aquaflow meter. I have built my wife a custom rig with watercooling using all thermaltake stuff except for a danger den block for the 7800 GTX card.

Nice...pretty long loop; what are you using for a pump, and are you using a heater core on that setup?

The base system is teh Thermaltake Big Water SE which has an improved pump compared to the older Big Water system.

I have two radiators in teh custom rig. One is at the back of the case, other is the Aquabay drive bay radiator. I also have an Aquabay resevoir and Flow indicator in the drive bays (which is why the loop is soooooo long).

Excuse my n00bness, but what is a heater core?

Other specs on teh DIY rig u see:
AMD X2 4600, 2 Gigs RAM (forgot the specs), 500 gig Hitachi Deathstar SATA II drive, Plextor SATA DL DVD Burner, Geforce 7800 GTX, PC Power and Cooling 510 PSU with green sleeves from FrozenCPU, ThermalTake Armor case

No OC'ing yet, hell, rig is not even used for gaming yet for the most part

A heater-core performs a similar function to that of a radiator, but are much more efficient at heat dissipation and offer better flow characterisics (less restrictive). They are best suited to reside in a rig that has a longer loop, i.e. CPU, GPU'(s), and NB waterblocks.

post a link for one please trickdaddy

This is not accurate information. A heater core and a radiator are essentially the same thing and the names do not denote any difference in efficiency, rather the difference in names is used to denote the purpose for which they are designed.

A "radiator" works on the principle that you are trying to cool the liquid running through the radiator by blowing cool air through the coils. This heat is transfered into the air and out of the system.

A heater core on the other hand is design to run hot liquid through it so that the air that blows through it can produce heat for some use such as warming the passanger compartment of a car.

In the case of Danger Den's heater cores, they sell automotive heater cores for cheap cooling solutions. One of the reviewers on the site actually says that they have the same heater core in their 77 Bonneville. The radiators of their own design are more expensive.

So essentially they are both radiators used for different purposes. The thing to keep in mind is that a heater core is designed with the assumption that there is a plentiful supply of hot liquid to produce heat in a system that is not trying to disipate all of the heat generated, so a heater core does not need to be efficient at releasing this heat into the environment, it just needs to produce enough heat. A radiator on the other hand is designed with the idea that you are trying to disipate as much heat as possible out of the system and into the environment. With this in mind they typically are designed with wide thin louver fins through which the cooling liquid travels allowing efficient disipation of heat. So whatever the name just make sure it is designed well for disipating heat.
