hey wanna buy a hercules monochrome graphics adapter. they pwn anything.
Well, except color. But come on! Color is SOOOOO yesterday! face the wave of the future!
Who needs 3d graphics when you can display TEXT! yes, thats right, the HGC has the much touted TEXT display mode. Display your reports in super high 80x25 text resolution! Amaze your friends!
WARNING: ensure friends have trouble distinguishing color for maximum effect.
Besides, sometimes you have to take a step backward(or 300) to move forward.
Alright, ANYWAY....
I can't really suggest anything better then what you already have. I don't personally play any super new games (I've been playing games so long I started noticing repetition in themes and story).
Right now I'm using a GeForce FX 5500OC AGP.
What exactly are you trying to do? What games do you play? These are all important factors! Of course, any newer card will help, the question is simply which will help more, and that banks heavily on your answers to these questions.
