The Ti4200 at $60 is a one-off offer at an online auction site
in India. It was a 'Quick Buy' item, XFX brand and declared
as new. I've bought it, though it may take upto 2 weeks to
arrive. I've often bought from this site and haven't got burnt
so far (fingers crossed).
Yes, auctions can be a gamble.
The 9600 Pro is out of my price range for this purpose (kids'
computer). There was a Ti4600 for $90 some time ago but
I missed it.
IMO, $90 for a TI4600 isn't worthwhile. It too is slow at
DX9, and the giant size of the card is excessive relative to
it's performance. I'd sooner get a 9600 Pro.
A couple of further questions please. Will the 64MB RAM
size significantly reduce performance compared to 128MB ?
Yes, IF the game needs more memory. Many games allow
adjusting the eye-candy such that you may be able to
accomodate for the lesser memory. For example, Doom3 ran
faster on a Ti4200 128MB at stock speed than an overclocked
Ti4200 w/64MB, but the settings and config file adjustments
can cancel the difference, but of course at lower image
quality.
It is worth noting that the last TI4200 128MB i had (a
Chaintech) overclocked poorly. It only allowed about 8%
over stock speed. Contrast that to a Gainward Ti4200 64MB
that o'c a little beyond TI4600 speed. Even so, today I'd
choose a card with 128MB, except for playing older games.
TI4(n)00 series simply isn't optimal for new games.
Also, how does the 9600 Pro compare to an FX5700 U ?
9600 Pro is better. I'm not 100% certain but believe the
FX5700 U isn't much if any faster than a TI4200. They are
in the same ballpark, IIRC. For the most modern DX9 games,
nVidia FX5(n)00 cards aren't so good as ATI's at similar
price-points until the nFOrce Geforce 6(n)00 series. For
DX8 games they're fine, but so is the TI4200.
