I have no AGP slot in my computer (please do not criticize, for I am building a new computer some time this summer.) But for now I think I am going to need a PCI replacement. I was wondering which would be better, the GeForce4 MX 420 or the radeon 7500. I know they both are equiped with 64MB RAM, but the radeon's is DDR.(not sure if the 7500 is a 128bit memory bus, thinling it is 64bit.) I do have a Geforce 4 MX420 now but Ithink I am going to have to replace it because, for instance, I switched memory banks with the ram chips and after that the GF will not display any image and have to switch to integrated S3 This has happened once before when I switched hard drives(both had run this card previously) but when I switched back to the main hard drive it wouldn't display any image, but with some tinkering I got it to work, just can't remember how) So I am thinking of replacing it and I want the better of the two for the games I do run. Like, MOHAA, Deus Ex, Unreal Tournament, Giants, and a few others. Any help would be appreciated. Thanks.
