For 20K could u guyz suggest a good proc.(AMD) with MOBO and good pci-e gfx card. Want to play DOOM3 at high setting. If you could suggest a mobo which supports DDR and not DDR2, then it would be fine as my friend already has 2gb ddr 400 RAM. Well his current config is as follows: P4 2.0Ghz I think 845 mobo Seagate 80 gb pata hdd 400W Coolermaster SMPS 2GB DDR 400 RAM DVDROM ,CD-RW, FDD, etc. So could he use HDD with new mobo?
