Thought I'd post some links for ya'.
This link is a good one for you, I thinkthe grafixguy
I have a socket A board.
Regardless of the mobo-maker, the onboard video, in your case I think being the nForce2 400 chipset, will not compete with the performance improvement of a video card to replace it.
AGP 8X Technology
AGP 8X is the next generation VGA interface specification that enables enhanced graphics performance with high bandwidth speeds up to 2.12GB/s and twice as fast as AGP 4X.
indicates you should buy one that will take advantage of your mobo's capability.
This year's crop of mobos has improvements beyond the AGP (PCI Express, for instance) and faster FSB speed limits (yours is 400 Mhz) but since you have a limit of 3+ Gb's of memory (with 1 Gb installed) and a budget that is realistically capped at/near 150 usd,
I'd recommend a video card installation as step one.
btw, here are memory cards to consider, also
(try to match exact the present one(s) if possible, for best performance. Same manufacturer, and each of the specifications on your presently installed ones.
Check for the ASUS recommendations for size, location, etc.)some memory card links
This site seems to understand the nuances of your board, and overclocking
is yet another way to (free of charge) upgrade performance.
Proceed carefully, since it is a kinda delicate process you want
to accomplish after researching and practicing.AMDboard.com
A couple video card makers are:ATInVidia
advice about both is available to read video card information
Opinions as to what is best with always involve those two makers.
My opinion is to use an nVidia on your mobo.
It essentially will power off and overide the onboard chipset when you install it,
and replacing nVidia technology with the same might be an advantage in this case.
