I want to know which of the following graphic cards can be installed in my system?
They are:
1. 256 MB XFX NVIDIA GeForce 6200 256MB DDR2 AGP 8X GRAPHIC CARD
2. Nvidia GF 7300GT 512 MB AGP 8X Graphic Card
3. PCI 128 MB DDR ATI RADEON 9250 SE TV Out/DVI
4. Asus 128 Mb 2x/4x/8x AGP VGA Video Card GeForce FX 5200
 
I am asking this question with particular reference to my computer's
1. Processor(Pentium - III 700 Mhz)
2. AGP slot (2X)(3.3 volts)
3. SMPS Wattage(235 watts)
 
Thank you

I wouldnt bother... seriously.
 
What do you want a graphics card for?  
 
Any game that you'd expect to be able to play with a Pentium 3 CPU would need to be so old that no modern AGP graphics card would make any difference. You'd have a graphics card far too powerful for the CPU...  
 
Whats the PC's main purpose going to be?

The main purpose would be for mid-range graphics gaming not for very high-end games such as crysis but for games such as NOLF2, HL-2, DOOM3 and so on. That is, games which have been released around 2003-2005

Id be extremely surprised to see a 700mhz P3 with 256MB Ram capable of playing HL-2 and Doom 3... seriously.  
 
You might want to consider upgrading the whole lot and buying a low spec modern machine... which will power those games fine.  
 
Upgrading an old system like yours wud be like flogging a dead horse.

Hello,
       Thank you for your reply, but what I want to really know is which of these cards could be installed in my system
        Could anyone answer this question Please.

I think, in theory, any agp card *should* run, albeit at reduced speed (2x). But truly, it is a complete waste of money, and you're not going to be able to run any of the games you want to. If you feel you must throw away your money, go ahead, but you're still not going to be running those games at playable speeds (or at all, perhaps).

I think you will find that any of those listed will work. A 4x or 8x card will step down and work at 2x.

I agree man, it's really time for a whole new system.  700 mhz is too slow unless you are running ancient games.  Sorry dude, but I'd save up for a newer rig.  We can help you price out a budget rig if you like, but I would not recommend a video card for your system as upgrading your system would be a waste of money.  It's too old and the parts are likely overpriced due to lack of availability.  

Guys,
       Thank you for the replies anyway, Bye.

well in this case i would def go for the cheapest so you wont feel so bad when you find out just how crappy that PC is for any kind of gaming (unless it's for games made around 2000-2003)!
 
goooooood luck with your choices!

I dont think the OP truly understands what we are telling him here.  
 
You need a faster CPU and more RAM to play those games. It doesnt matter what graphics card you're using... the games simply wont work and you'll of wasted your money on the graphics card.  
 
A P3 - 700mhz system will run games from 2000-2001 adequately... but nothing newer.

if you are on a super budget you can get a $200 or less refurbished system at tigerdirect or directron with pci-e slot which would be a much better starting point than trying for a video card

Perhaps posting on CraigsList for a Looking to buy very old AGP or PCI graphiocs card.  Willing to pay up to $5 and will pickup.
 
Maybe somebody has one in a drawer unused someplace they don't value.
 
But you system is so old that you would have a tough time getting more than $25 and maybe $50 if you were lucky for it.
 
I've had more powerful systems (sans hdd) that I've give away gratis because I did not feel they were of sufficient value that would let me sell them in good concious.
