Whats the differance between a Lada and a porsche??
Yes of course it would make a differance. I have just upgraded from a 32mb to a radeon 128md and the change in playing games etc is startling!!.
Assiming you have an agp slot then I would say go to pcw, they are offering the card I got for £65. If the offer is closed the brown box range has a sparkle 128mb card for the same (nvidea card)
