in a few months, i'll have raised the cash for a new system, but i have a few problems and debates that i need to resolve for the time being. here are the two scenarios, a.k.a my possible setup. comp 1) AMD 5600 Athlon Dual Core 2.8 ghz 1 gigabyte corsair brand RAM Nvidia Geforce 8800 gtx 640 mb 160 gig hard drive 550 watt power supply or comp 2) AMD 6000 Athlon Dual Core 3.0 ghz 512 mb corsair brand RAM Nvidia Geforce 8800 gtx 640 mb 160 gig hard drive 550 watt power supply. my trouble is i don't know whether or not i should get 1 gig now and a weaker processor, or the better processor and add more ram later. my main worry is that although i will have a stronger processor in the second setup, it'll have trouble picking up the slack considering i'll be attempting to play Call of Duty 2 and other games that are a little bit needy in terms of RAM. not to mention, running XP on this system with only 512 mb of RAM might not work out for the best. if anyone can prove me wrong, please do. i don't want to make any big mistakes with this computer because it's really my one and only shot. either way, whichever one i pick, i plan on buying an addition 4 gigs to throw in. its merely a matter of which system i should pick so that it can tide me over until i get the new RAM cards. and if there were one thing you would change in this setup, what would it be? your input is greatly appreciated.
