Hey guys,
I Have a Dell Inspiron 540
Config:
intel core 2 quad
2.5 GHz
RAM 3gb
Graphics Card: ATI Raedon 4300 512 mb
memory : 500 gb

I want to upgrade it to
4 gb of Ram
1 gb of graphics card
1 tb of memory

Can i upgrade to these and can you suggest me a good grahics card( not too costly)

The difference in performance between 3Gb of RAM and 4Gb of RAM is so negliable it isn't worth doing.
Depending on the games you want to play you may not notice a difference between 512Mb of graphics and 1Gb.
As to 1Tb hard drive, again, performance wise you will not notice a thing, unless your current drive is chock-a-block.

What do you want to do with the machine?

I am a gamer and some games i play work pretty slow. So i need a better graphics card what do you suggest. I guess i've agree with you on changing the RAM.
And about the 1 Tb hard disk, my current one is filled, so i want additional space thats why i wanted to know if i can. Im not a pro i've never open my CPU i dont know if there a additional slot. Overall i want a better gaming pc
