Ok im on quite a tight budget, i currently have a AMD XP2400+, 1G PC3200, 256MB PC2700, X1950gt (AGP). I would like to upgrade the mobo and processor (ok for £100 im not going to get much) but still be able to use my DDR ram and Agp gfx card.........whats the best i can get for my money that would give me the biggest improvement over what i already have........thanks
