Onboard video chipset

The Ati radeon 3000 is much better than the nvdia 7025, gaming???, there´s no way to play a decent game with theses gpus.
With an Ati radeon 3000, you could play 2006 games....

means i can only play games upto the year 2006??

one of my frieng have nvidia ge force 6100 onboard grafix .and he plays games like nfs prostreet and much more.

Yes there are some newer games that you would be able to play on LOW SETTINGS(and some in high like win Minesweeper......., just kidding), but if you are going to use the computer to play games, I would recommend you to spend some money and get a new gpu...

Of course without knowing your cpu, ram, etc... it´s very difficult to tell you a good gpu for the money, but there are some cheap gpus like this one

that would make a great difference..

Is it a laptop or a desktop?
If it's a desktop then i would look into getting a new graphics card.

gaming is my preference as im upgrading .but not the only reason for upgrade. is really ati better than nvidia would ati 4200 be fine enough to play medium end games 

secondly how much video memory ati 3000 and ati 4200 provide do they provide upto 512 mb .

desktop.can't buy graphics card now .would require more expense.

With the ATI you could play some low end games. It´s a better option than the Geforce shown. Video memory? These kind of gpus won´t be able to use more than 256 Mb, so no matter if you see "up to 2 Gbs of memory shared"...

Why don't you list your full system specs,what games you play and how much your budget is?

Then once we know the details we can help you get the best graphic card for your needs.If you using a desktop and you want to play games theirs really no point in having the use the intregreated card.

cpu
amd athlon 2 x2 245 to 255.
motherboards
MSI 760GM-P33
ASUS M4N68T-M V2
Msi 740GM-P25 .

500 gb sata
2gb ddr 3 ram

samsung dvdwr.

What games do you play and what resoultion?

Do you have the money to upgrade your GPU?

Really any low budget card is way better than the onboard graphics.Something for like $60 would double if not triple your graphics performance.

ok.first ican go with onboard then can i add more graphics to it???shuoul i go for ati chipset or nvidia keeping in view of the future graphic card compatibility???

Yea thats awlays good.What you need to know next is what's the make/model of your power supply?

do power supply differ for different kit??
