Im looking to upgrade my computer a bit for something with a bit more power. I need a processor, motherboard and graphics card, some memory i already have 1gb (but this is on a motherboard for an athlon 3000+ processor, so i dont know if this is compatible with a new one?) Ideally i would be looking for something under the £250 mark as i havent much money to spend on this. Im mainly a programmer but do a wee bit of video editing and 3d work but not much. Oh and the components would probably have to come from dabs.com or misco or a similar uk supplier. Any suggestions as to what i could get?
