Need help upgrading my Dell Inspiron 530s

[cjk086]

Hey,

I bought this Dell Inspiron 530s from Dell 2-3 years ago. I didn't know what I was buying which was a very stupid mistake. I want to upgrade pretty much everything in it. My absolute main goal is my RAM and Video card. My current card is:

Card name: ATI Radeon HD 2400 PRO
Manufacturer: ATI Technologies Inc.
Chip type: ATI Radeon Graphics Processor (0x94C3)
DAC type: Internal DAC(400MHz)
Device Key: Enum\PCI\VEN_1002&DEV_94C3&SUBSYS_04021028&REV_00
Display Memory: 1012 MB
Dedicated Memory: 245 MB
Shared Memory: 767 MB
Current Mode: 1024 x 768 (32 bit) (60Hz)

I want something to play new games like Left 4 Dead 2, Napoleon: Total War and Mass Effect 2.

I am looking at the Radeon HD 4650 512MB 128-bit GDDR2, but I highly dought it would even fit into the slot. http://www.newegg.com/Product/Product.aspx?Item=N82E16814102829


The other card I am looking at is the Radeon HD 3450 Video Card - 512MB DDR2 : http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3720545&CatId=1826

This is the one I want to know if it would fit. I have the default power supply that came with the computer, so I do not know if I need a more powerful one. Please please help somone who has no idea what to do. Thank you in advance.

Is there any other model that is better for my computer without a power change?

I'm taking some tips from delluser, he answered my problems before. On Newegg there is a 300W Seasonic PSU for TFX or something close to it. Anyway delluser told me to upgrade to this if I need to, I haven't tried it yet but just to let you know. This 300W should supply power for youe 4670 and maybe even the 5570.
