Best AGP 4x Gpu for under $40

[compaqguy]

I have a Compaq presario 5123sr
1.0 GHz athlon Thunderbird processor
756 mb PC 100 sdram 
Stock Compaq Uwave2 motherboard
Windows xp installed

I have the ram maxed out and I have a 64 mb agp gpu already in it.

The performance is decent just trying to get a little more juice out of it.

Could anyone point me in the right direction?

Also should I buy the 1.3 ghz athlon Thunderbird to max out the processor?

i think whatever you try to upgrade at this point if not worth it... you can get a much faster system completely for ~$150 or a second-hand one for 100.

I agree with laviniuc. the system is just too old, and if your really want better performance, then you will need a full system upgrade...
