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?
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.
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/7000/77...
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.
