What's a better graphics card, agp 4650 512 ddr3 or agp 4650 1gb ddr2?

use=video editing (pinnacle studio primarily; might get into HD);
power supply=460 watt, cpu=p4 3.0,sys ram=3.5 gb;xp pro 32 bit
monitor size that I have = 21 inch crt


both are $100+. [I know . I know, get a PCIe (but my mobo is old and I dont have enuf money to get a whole new system; this is to tide me over)].

+EDIT: assume that the 512 can be had for $80 instead of the $100. Just found this on newegg.com

yeah, I like the 3850 jtt suggested at that price. I'm guessing it may even be faster than the 4650. Might even pick me up one!

At first, I thought that a 3850 wd be a *lesser* model - due to the name value of the model - but I just checked Tom's GPU hier. chart, and found that a 3850 is actually rated higher than the 4650, and it is equal to or even less than the price I was looking at with the 4650.

good suggestion. I will consider it.

EDIT: The maker is called Sapphire. anyone know whether this make is good ? (I saw the bad experience with diamond above).

also, when the reqs say that a 450 psu is needed, how is the other devices and load taken into acct? what does the req assume is connected to the psu, a mobo (what kind?; there are many), cpu (what kind?; there are many cpu's), one optical and one HD? What if you have more than one HD?

my 460 watts will be connected to

a p4 3.0 cpu
a dell xps gen 2 something mobo
an ide dvd writer
at least two , and maybe-probably 4 , 5, or 6 sata HDs


$93
