Anyways regarding the budget query well i guess that would entirely depend on the extent of duty that is reduced on the Imports of foreign goods.....so if a drastic change has been made then u definetly must look forward to get PC components at quite cheap rates

Also heres a runnign thread on it

Also u meant the Asus K8N-E Mobo that u plan to buy has a Onboard Nvidia Nforce 3 250Gb chipset...so consider it givin ya a max of 64Mb shared Vram (i Suppose)
plus dun go for a Fx5200 Gfx card if and if only u are short out on budget....or else consider Ati Radeon 9600Pro Rather which i suppose around 7k
