I want to ungrade my PC, so upgrading has Rs. 12000 budget. So can anyone suggest a good mobo, processor, cabinet and RAM package (and also AGP card if possible) which will be under my budget, considering that I use my computer mainly for multimedia puposes and playing games. I am currently thinking of a good AMD 2400+ processor but am not able to decide on the mobo,RAM and cabinet. So please help. Also, can any one tell me how much my old Celeron 500 MHz processor, Intel 810e motherboard and 160 MB(128 MB + 32 MB) SD RAM fetch me from my dealer if I sell it to him.
