Yes some SS7. and even Intel LX motherboards, had problems with power requirement of AGP cards.
That FIC 503+ and the 503A do not have these problems however.
What is strange is that in boards that have problems, they also had the power problem using V3 3000 AGP.
The GF2 series cards actually use less power than the V3 3k AGP, and the original TNT2 or GeForce cards.
Still have an old FIC K6-2 system with a Voodoo 3 2k that the kid uses.
Had a couple FIC SS7's in the old days....
As a gamer, I tried many different solutions to get the K6 to work, as the V3 3k in my machine wouldn't cut it.
The only upgrade that was worth it was going from V3 3k AGP to GF2 MX. Nascar Racing 4 was my goal.
In all games, picture quality was improved. In the worst games, fps speed with the MX was at least the
same as the V3, even if the V3 used Glide. In the best games, like N4, framerates doubled even at higher
resolutions. The other thing the MX now allowed was the ability to run games that required a 32 bit 3d card,
such as Links LS and Myst III. Sure, at 32 bit the resolution and quality needs to be turned down, but at least
with the MX you can run these games using 3d hardware, which is something you can not do with a V3.
Also note that if using GF2 cards with SS7, you must use older nvidia drivers (6.27? or 7.58) or performance will be worse than V3
Don't know what CPU you have in that FIC, but for around $30 (TigerDirect yuck), you can get a K6-2+ 450 that will run at 600MHz.
3dm2k (not 3dm2k1se) numbers (all default):
k6-2+ 450@600
V3 3000 AGP scores 1698
GF2 MX using newer 10.xx drivers scores 1246
GF2 MX using drivers 7.58, scores 3221 at 175/166, or 3458 at 190/200
Nascar Racing 4
Voodoo3 3k AGP 800x600 = 16fps (all options down or off)
Voodoo3 3k AGP 640x480 = 21fps (all options down or off)
GF2 MX D3D HAL 1024x768x16 = 24fps (some options on, and image quality up a little)
GF2 MX D3D HAL 800x600x16 = 27fps (some options on, and image quality up a little)
GF2 MX200 is slowest GF2 type card.
A GF2 MX is faster then a GF2 MX200.
GF2 MX 400 is faster still.
GF2 GTS comes next.
Then GF2 GTS-V tops out the very low end stuff.
For $50, the GF2 GTS-V seems like the best bet, as it could go into a 1GHz machine later and still perform somewhat.
