cards and onboard gfx?

Probably a stupid question but....
i would like to know why does a graphics card have its own RAM?

and

with my specs...would i be better off getting this card (ATi Radeon X1650 PRO 512MB PCI-Express) for general comp use.(only for MMORPGs-with budget of ~£20-35)

    What games exactly? Any dedicated graphics card is better than intergrated. Just make sure your PSU can handle it.

  2. Yeah, just get a low end 8400GS and OCit. Much better than integrated. The 8400GS is about $40-45=~£30
  3. oh thanks for the info

    is the 8400GS = nVidia GeForce 8400GS 512MB PCI-E?

    "This item isnt good value for money, especially over the 256MB Version which is £12 cheaper and faster. I have tested both this card, and the 256MB version by XFX on 3DMark06 and the score difference was surprising, with the 512MB card scoring lower than the 256MB card! This is because the DDR2 Ram is slower (667mhz) on the 512MB model, whereas the 256MB model uses 800mhz DDR2 memory, which is 20% more efficient!... Save your money and opt for the 256MB version."

    what do you think?
  4. Sounds good for the $, get the faster RAM GPU, the 8400gs.
  5. is there a difference between Inno3D Nvidia GeForce 8400GS 256 and nVidia GeForce 8400GS 256MB PCI-E?
  6. Do you have links for them? Generally it's just a manufacturer difference. The reference chip (8400gs) is standard, but the way a manufacturer equips the card is usually different. Some of them use the minimum RAM and some use faster RAM. It all depends on what company and what they are trying to offer the consumer.
  7. oh right i see
    oh right i see
    this is the inno3D card

    The nVidia GeForce 8400GS 256MB PCI-E would be a new one from a good site
  8. The benefit of buying a new GPU is that you'll get the full warranty from it. If you buy used, most manufacturers don't cover the 2nd owner, so you might keep that in mind when buying.
  9. Right...i should prob get a brand new one then.

    I was readng about SLI on this froums stickey and it says that "Currently, GeForce Boost is only supported by GeForce 8400 GS"

    Is this on all the cards or is there a specific card that would say has GeForce Boost?

    Is there a brand for 8400GS 256MB you recommend, i am currently looking at a XFX one because it is within my budget inc delivery.

    Manufacturer XFX
    Chipset 8400 GS
    GPU Clock Rate 450MHz
    Shader Clock 1200MHz
    Memory Clock 800MHz
    Memory 256MB DDR2 SUPPORTING 512MB
