graphics cards
 

I just got a new computer with what i thought was a good graphics card at 256mb. This although, seems to only be able to play the most simplest games with any clear graphics. Ive read on other forums that 512mb doesnt make much of a difference. Is that true? So is there any way to tell if my motherboard is compatible with the new crossfire technology. And how does this work? Do you just have 2 graphics card slots?

We need more details before we can give any defenite answer.
As for your MB, search the manufactures website (or your manuals) for info on that.
Crossfire is ATI techology, NVidia has SLI, the MB's chipset can only support one of these, if it does at all.

It sounds like you need to get rid of your old videocard and buy a new one. You don't want to get into Crossfire technology (which is using 2 videocards at once) unless you're an enthusiast. And yes, those people are right, the memory (MB) on the videocard doesn't have a whole lot to do with its performance.

Run SIW and it will tell you all about your computer: http://www.gtopala.com/download/siw-setup.exe

Ok, this is the pc i have.....Dell Studio Slim Desktop PC

and this is what it says for the expansion slots I have.....
PCI: 1 Slots
PCIe x1: 2 Slot
PCIe x16 (Graphics): 1 Slot



Im dont know much when it comes to this stuff. Can anyone give me some insight as to what kind of graphics card I can get for this pc. Ive heard people talk about a low profile card. Do I need this?

what do you mean by not clear? Are you saying the picture is blurry? Usually an underperforming video card will drop its frame rates and make for jerky animation, but blurry pictures sounds like a different problem to me, possibly even with the monitor.

Of those expansion slots you would only want to use the PCIe x16 slot and I'm preatty sure that you will be limited to low profile card.
You will also be limited by the 250W psu.
When I googled this problem among other things this linke here came up Question on Video card for 250W power supply Dell Stuio Slim - Computer Forums
