okay i have got myself very confused with mobos and graphics cards.

here is my Mobo : Link

and here is the graphics card i want: link

Now are these two compatable?

And what does the GDDR3 mean, is it like ram and DDR2? This is where i have got myself all confused.
and is an Intel Core 2 Duo E6550 any good at overclocking?

any help with this would be amazing

GDDR3 is video card ram. Its just like your regular system ram (like DDR2), but its built onto the video cards, and performs faster then system ram.

The video card you want is PCIe x16, and your motherboard has two PCIe x16 slots, so they are compatible with each other.

All Core 2 Duo processors are very good at over clocking. As long as you know what your doing, you can over clock it pretty well.

Thanks for clearing that up for me, now just have to order the parts and put it together.

Also I might like to add, ask Parahana Joe about 6550 overclocking Hes got one if i recall. Or check his showcase in the Computer Hardware forum.

The P5e is i remember is a pretty good overclocker, Im sure youll be satisfied with your results once u crank that C2D up a little

I just bought a TT DuOrb for my 8800GT and one of the bearings on the fans are bad(VERY noisy). So i was wonder if I could install a fan controller for it. If so what kind of controller will I need, basic 4 pin? And how will it go on?

Any fan controller that has an input for a molex (4pin) will work fine, that is if the du-orb uses a molex for it's power and not a 3pin connector.

So i just plug it up and BAM it works just like that?

Exactly, all a fan controller is, is a relay that controls how much power will go to what ever fan is plugged into it. Most fan controllers will support 4 fans and up.

Even if the one you want doesn't have the correct pin configurations at the connections, there's a good chance that you can buy converters separately...or they might even come in the package with the controller.

I'm not sure how hard it would be to attach a video card cooling fan to a fan controller though. It uses a different plug then the standard 4 pin molex or 3pin fan connectors.

I have a fan controller in my computer. It has one power cord that plugs into any molex connector, then you can plug 4 fans into it and control them separately. Depending on which way you turn a nob, it makes that specific fan go faster or slower. Mine came with both 4 pin molex and 3pin fan connectors, and it was only about $12.

i've been looking through a lot of motherboards to purchase,and most of the ones with two or more pci-e x16 slots are, as stated on their product webpage, crossfire enabled or something similar. so i was wondering whether a sli configuration would still work on them?

As of now, the only motherboards that oficially support SLI are the ones with nvidia's chipsets. The newest ones are the nforce 7 series which include the mid end and more affordable 750i motherboard, and the high end 780i and 790i motherboards, which are more expensive. So for example, intel's x48 chipset does not support sli, only ATI's crossfire.

Hope that helps

i got another question. if a psu is sli certified will a crossfire configuration work on them as well? or will it be rather unstable?

yes, it will work. The certification means that Nvidia tested on that PSU for SLI. ATI might not have tested with it, but it will still work fine. There are some high end PSU's that have no certifications that are better for SLI or Crossfire than some of the ones that are certified. Basically a high quality PSU with enough watts and enough amps on the 12V will run SLI or Crossfire fine, regardless of certification.

thanks.
