Need help on configuration.

Hi all,
I presently have a P4 machine (1.8 ghz) with a Intel Motherboard and an external graphics card (AGP) with 1 GB ram.
I have noticed that presently most of the games that are being released are releasing for Windows Vista! I was actually avoiding to install Windows Vista as I was told that it is quite resource hungry and moreover because I did not want to invest in a 64bit CPU at that time!
But I have learnt that games like Ghost Recon, Halo 2 etc. are releasing for Vista only so I am contemplating whether to upgrade or not.
My budget is limited so I would be grateful if you could help me by recommending a core 2 duo processor and a decent motherboard.
Do you think I should take a motherboard with AGP slot or PCI express slot?
My budget is approx. Rs. 10,000 (for CPU and motherboad)

At present there are few games which are actually Vista only games.2 falling in that league are Halo 2 & Shadowrun.If you do feel the need for upgrading your system now then I suppose you'll also need a ram shift which means you'll need to spend additional amount on DDR2 based modules.So fix a final budget then we can go about it accordingly.

Also AGP is almost phased out right now.Rarely would you see a Core2Duo based motherboard which would have AGP based slot.So ideally wise to go for PCI-E solution considering that most recent board have it as a standard expansion slot.
