Ok so im brand new to building computers so i need a little help with this At first i wanted to buy a Dell inspiron 570 and just install a HD 4670 on it. I really want to build my own and not go with the 570 but i have no idea what i need. I need this computer for some games like gta 4 ,mw2 and a free game called combat arms there are also a lot of other games i want to play but those are the main ones. My mother said she dosent really care what i get as long as it is under $500 ( im not sure if that includes the monitor or not. she wont tell me ) and I dont care if the cpu is intel or amd or if the gpu is ati or nvidia.
