hi, i just got my ati radeon 9800pro and i need to get a upgraded PSU (looking at 400 watts PSU/case combo) for my dell. I just talked to dell support and they said that the mobo the computer came with is only good for up to 300watts.... so now im looking into getting a new mobo and i need help. im not that computer savy so i would like to know what would be a good choice to get the most out of my new vid card. I know that the mobo in my comp now has AGP 4x... i kno i need AGP 8x. I have a pentium4 @ 2.4GHz. Also, how involved is it to switch to a new mobo, besides reconnecting everything? Any major problems to look out for?Please any info/recomendations would be great. if you need to know any more specs on my comp LMK.
