Jabil Tabor Pentium II BX Motherboard: Part Number 4000444
200 W Power Supply => Supplied by Gateway
I have no budget. The intended use is for gaming. I play some of the more
modern, graphic intense games such as Simcity 4, Dungeon Siege, Warcraft
III, etc.
The CPU is too slow for significant benefit from a video card upgrade.
The motherboard only accepts older AGP1 (2X) 3.3V use... newer cards
will work, but are a bit of a waste.
You may find you're in need of more memory too, but your motherboard
only supports lower-density memory, might be expensive to upgrade the
memory and that isn't the primary bottleneck "yet".
The power supply is also inadequate for high-performance video cards.
You can't just replace the power supply either if you have the common
GW midtower case, it uses a proprietary form-factor power supply.
You didn't mention your current video card so I can only assume it's
of the same age, speed as the rest of the system. To more directly
answer your question, if it were me, wanting to only upgrade the video
card, I'd look for the cheapest Geforce3 Ti200 I could find. Failing
that, perhaps a Radeon 9100. Either will be bottlenecked by the rest
of the system, quite severely. They're both around $50-60 (low
internet pricing). You could instead get a Geforce 4MX for around
$40, or a Radeon 9200 for $50, but they would be slower on your
CPU-bottlenecked system. To reduce the CPU bottleneck you could try
upgrading the CPU but at this point in time it's not cost-effective,
especially since you still need the video card.
On the other hand, the above is only if I had some odd emotional
attachment to the system... realistically the whole thing needs
replaced for significantly higher performance. Even a system such as
an Athlon XP2100 with nForce2 integrated video, would run circles
around your current system with (the fastest video card on earth
plugged into it), which of course wouldn't work anyway because of the
power supply. I'm not entirely sure that any of the above video cards
will work with your low-wattage power supply either, so I'd buy from
someplace with a good return policy.
