Hey, I'm a gamer who wants to upgrade from a GeForce 2 MX 32MB. I have read some posts about upgrading, but I'm still unsure. I have a single 867 Mhz G4 with 1.25 RAM. Now I've heard that if I get a high video card, I will waste my money with a vid card that outperforms my processor. So what I'm asking is - which video card will best suit my processor speed? I am looking at the Radeon 9000, but I'm just a bit confused. Are there two kinds? 64MB and 128MB? Will the 128MB be wasted money? Please help me out. Thanks!
