I still dont no what to do for the best

In 2008 i got a new PC with Vista home premium32bit edition and had nothing but problems. Im not sure whever its the OS or my PC it self. The problems are mainly with the graphics card and vista not seeing it properly but it does work as i can have games like bioshock and dead space on full graphics. My graphics card is a ATI3870X2.My mother bord is asus(something or other) with nvidia chip sets on bord would this also interfear with my ATI card cos of the makes of chips and card are different. Should i have gotten a nvidia card to go with the nvidia chips and a AMD pc to go with the ATI card?. I have actualy pre orded windows 7 pro. I am stilldeciding whever to put win7 on this pc or buy a total new pc in january time.Also win7 pro has the option to put 32bit or 64 bit drivers on which one do you think be best.

As well my Graphic card is sapphier 3870 X2 card but when i format my PC with vista it shows in the updates that its a asus card but the only asus i got is my mother bord. So it does look like it is vista not looking for the card properly.

Thanks for any advice.

I don't quite see what your problem is. What do you mean Windows is not detecting the card properly? If you can play games at full detail just fine, you don't have a problem. And an ATI card will work fine on Nvidia motherboards and vice-versa (just no SLI or Crossfire)

If your problem is that Windows Update shows an ASUS video card update, let me help you out: NEVER rely on Windows Update for new drivers. Go to ATI or Nvidia or the part manufacturer to get the latest drivers. You can't help it if Windows Update misdetects your hardware, but you don't want their drivers anyway.

Umm... I'm fairly sure an X2 video card is still considered Crossfire, even though it's using a single PCI-e slot. So, I'd guess that's your problem. I would guess that your X2 card is defaulting into single card mode, even though it's an X2, because you don't have a Crossfire capable motherboard. And Nvidia won't support Crossfire; it's the enemy as far as they're concerned. So, yeah, that Nforce/Nvidia motherboard chipset is, most likely, the problem.

As for 32bit versus 64bit, I'd go with 64bit. Problem with 32bit is that it can only address a maximum of 4Gb of ram, and system memory always gets addressed last. Which is why you only see about 3-3.5 GB of ram when you install 4GB of sticks, into the motherboard. 64bit, more often than not, can address more. I don't know about Win7, but with Vista it depended on what version of Vista you bought. Think Vista Home Pro could address 16Gb.

As for using Vista 32bit, you'd be much better off with WinXP.
