Help with Graphic's card and other small items

[Dark25]

Hey there, I currently own a Dell inspiron 530. I've had it for about 5 years now for gaming purposes and I would like a new upgrade etc Because i now cant play certain games now. I've got friends who know quite abit about this sorta thing as for me i do not. I'm mainly here to ask for a second opinion so any help is appreciated. I've already chosen what kind of graphics card I will be getting, some ram sticks and a PSU. I mainly want to know if these items are able to run with the dell computer or not, also would buying a new computer be better than getting new parts for this computer. I'll put down some info about the computer now also if you need to know more about the computer please say.

inspiron 530
intel(R) Core(TM)2 Quad CPU Q82000 @ 2.33GHz (4 CPUs), ~2.3GHz
3070MB Ram
DirectX 11
92.6GB Ram left.

Current parts i'm going to buy will be on the link below, I would like to know if they are able to fit in it.

If your Inspiron 530 is not the slim line version, the PSU and Graphics card should fit OK (assuming the board has a PCIe x16 slot). But be sure your board takes the DDR2 memory you selected, and not DDR3. They are not interchangable.
