Hey gang. Long time since I've posted, but I really want to get Call of Duty 4 and want to know what I can keep from my current setup towards a potential new one.\nAMD 2500XP\nBiostar M7NCD Pro\n1 gig DDR ram\n128mb9200 Radeon\n500 OC powersupply\n \nThinking the hard drives (IDE)..and the power supply are all I can really use towards a new build. Any thoughts? I want to go inexpensive if poss. What would you recommend for a decent but cost effective setup for this game? Dual core Pentium? GIve me some ideas if you can. Thanks.
