Hi guys.... although i dont know too much about computers, i'll do my best to tell u what i have and hopefully u guys can give me some guidance on what graphics card i should get. i have a pentium 4 640 3.2Ghz processor (the 64-bit one), rs400-A motherboard which supports pci-e and agp-e, 512mb DDR ram....those are the main things. I don't yet have a graphics card so i'm just using the integrated graphics at the mo(this is definitely not good) so I'm thinking of buying a graphics card tomorrow. I want to spend around £100. i'm thinking of going for one of the radeon X series cards. obviously some are too expensive for me.... what would be a good one to buy?? any ideas??
