Well, I dunno much abt this graphics card thing just would like to get a few things clear. - What are the different parameters that decide the performance for a graphics card? Is it just the memory (128 MB) etc. or are there other things too? - Are Radeon cards less compatible with programs than Geforce cards? - What is overclocking? What effects does it have on the a) Performance b) the heat production, and the life of the card? Please help. Thank You!!!
