Ok, first of all, Cobra thanks for all that info.
I downloaded 3DMark03 from futuremark and ran the tests. I got a pathetic score of 892. On all games except one I had only 2-3 FPS lol (I guess these have very high details etc.). The first one (Wings of fury) I had a good 30 FPS consistently.
This program also gave me some additional system information that I earlier had wrong:
CPU:
Family Intel® Pentium® 4 CPU 2.80GHz
Architecture 32-bit
Internal Clock 2.8 GHz
533.0 MHz
Memory: x2
Installed Enabled Size 256 MB
Form Factor DIMM
Frequency 333.0 MHz
Vid Card:
NVIDIA GeForce FX 5200
Ok, so now both of you and others have recommended the ATI Radeon 128 MB Pro card and an addon of another 512 MB RAM stick.
1. Would you change your recommendation now that I know its 2.8 ghz and not 2.6 ghz?
2. I searched Newegg for this card, and it came up with atleast five or more Radeon 9800s but which one am i supposed to pick? what are the differences?
NewEgg Link
3. This is expensive for me (as my whole computer itself only cost $700), so I need to know if this will last me atleast another 1.5 years of gaming... keeping in mind that upgrades of Lock On and other games might be out.
Thanks to all those who are helping me out. :)
