Buying a new video card

Hello,

I have one question about upgrading my old pc's video card. I am planning to buy Nvidia GTX 750 2gb gddr5 to my old pc and replace my old Geforce 9700GT(512mb).
My power source is 350 watts
Processor: Amd athlon 64 2x 4000+ 2.09 GHZ
Ram: 2GB DDR2
HDD: 160GB

I know it's an old pc and I wonder if buying such a good video card would actually help me and be all ok?

Thanks a lot!

 

You'll also have to upgrade the PSU.
Visit Power Supply Calculator to calculate the minimum power required for your PC.

Thanks for the reply. I've calculated as it seems, it asks me around 260 watts (minimum recomended) even with the GTX 750. I've heard some people saying that some of 750 require 300 watt PSU, some 400.

Even tho if I find 300 one and it goes all well with my 350 watt supply....The quesiton is, is it going to make any serious difference with the other old components my pc has? I mean, the graphic card is going to be so new/good compared to CPU/ram amount etc.

 

It's difficult to say whether a newer graphics card will make a visible difference or not as there are too many factors invloved. It comes down to what you use your PC for - if your a serious gamer or do video work requiring hours of rendering, yes. The newer card has a faster GPU and 4 times as much RAM - 2 plus points.
Also check whether your motherboard and version of Windows are fully compatable.

 

I am a gamer, yes. Buying it for gaming purposes. But always asking myself if it's worth it and will the graphic card work as it should with other low components my PC has...
It has PCI-express.
Motherboard is... K9N NEO - F V2
And I am using Win 7(32 bits) atm.

 

Modern graphics cards are like mini-motherboards - own specialised CPU, called a GPU, own RAM, etc.
The only further advise I have is to check the system (CPU & RAM), and graphics card recommendations, for the paticular game(s) you play.
I do not believe the newer graphics card wont work well with the existing components. Whether the improvement will be worth the money spent... I cannot possibly say.

 

Eldon has you covered.
I will add that you can look at your game's forums (or post the names here) to see if they are GPU (video card) or CPU (processor) limited on your system.

 

Thanks for the replies. I am a random gamer but loving to play stuff on max. (as max as possible). So I'd even try the newest games.
By the way, may I ask one more question...
I've one more PC upstairs...It doesn't have a GPU, would I be able to run on high-ultra or at least close to it(if I play the newest games that require a strong PC- GTA5, Witcher etc.) if I use GTX 750 TI in this PC:
Processor: AMD A8-7600 3.1 GHZ, 10 ulti cores
GPU: as mentioned GTX 750 TI GDDR5 2GB
RAM: Kingston 4GB 1600 MHZ(Might be even 1800) DDR3
HDD: 1TB
OS: WIN 7
