Can my PC handle Radeon 7750 HD

Hello, I have old PC and its not good but I want to buy a new video card because some games are not going good. I don't know much about computers and I need your help.
Info for my PC :
Motherboard: Gygabyte GA-945GCM-S2L
2 GB RAM
CPU: DualCore Intel Pentium D 940, 3200MHz
PSU total output is 400w max

Can my PC handle Radeon HD 7750? If yes will the video card be used with its maximum speed (because my computer is weak)? If not do I have to change something(PSU or more Ram memory or better processor) or its better to buy a new PC?

  1. According to gigabyte, your motherboard has a PCIe x16 slot, and will take a Radeon HD 7750. Your 400W PSU should be enough to handle the card as well since it is only a 55W part.

    You will likely need to update your bios to support the card though. Your system will probably limit that card a bit, but since it is an entry level card, it should not be enough that I would say don't upgrade.

    You may also consider increasing ram to 4 Gb.
  2. I don't get it what you mean with "don't upgrade" . Not to buy the video card , or not to upgrade processor or PSU ?
  3. Sorry, double negative there. I'd say go for the upgrade. Just make sure to upgrade the bios as well.

    Upgrading the bios I think will not help a lot. Reading the description there is nothing necessary. http://www.gigabyte.com/products/product-page.aspx?pid=2669#bios

    The only thing I am worried about is if I buy that card , can my PC use its maximum speed and preformance? Is it worth to put such video card on PC like mine ?
    Here I read system requirements for that video card but it says nothing about motherboards or cpu (because mine are old and not good), if that can slow down the video card or make it not work properly : http://www.amd.com/us/products/desktop/graphics/7000/7750/Pages/radeon-7750.aspx#3
  5. Your PC probably can't make full use of the card. That said, it will still provide a nice upgrade. At that price, I'd say go for it.

    If you don't want any bottlenecking to occur, you're going to need to look into a new system.
  6. Save your money for a more recent system.
  7. Save money get new good system.i will never take risk to put pci 3.0 in that 945 mobo.

    i mean as you know pci 2.1 and pci 3.0 has problem with pci 1.0.that is why and also there is no bios update for 945mobo.modern mobo like g31,33,41 has no problem because of pci exp compaibility bios update.
  10. How much amps on the 12v rail? It will be a bottle neck if you buy it, and there could be alot of problems with your old system and this realtively new card.
  11. Depends on the psu, but the rest of the system could bottleneck the graphics card
  12. thank for the info. I really appreciate it :) I will buy a new PC soon and will post the configuration here so you can advice me about the price if it is good.
