Need to run Old and New Games both

In update to Previous Topic

Need Help with Graphics and Motherboard .I mainly play older games (2000-2004) such as AOE-1,2,3 , Morrowind,Halo-1 and 2 and Diablo 1 and 2 .But need a Pc capable of handling Oblivion as well. Will use for 4-5 yrs.

Decided Components:

CPU-e8500

HDD-WD digital Caviar Blue WD6400AKS (640 GB)

500w PSU Corsair or Cooler Master

I had chosen graphics card as 9800 GT or HD 4830 ,but they don't seem to run older games.

Please suggest one that does and a compatable motherboard (imp). They should be easily available.

P45 based Mobo, I recommend Gigabyte ASUS or MSI...

Well 4830 better than 9800gt, but ye say old and new games, so 9800gt will be...

So i'll get the 9800GT ,but will that cause any problems ?

I had a post little while back ' effect of graphics card on older games '

Quiteguy in that gave reasons for non working of older games ,

but i need an answer as to go for older or newer card ?

Whats your opinion?

Only have Oblivion as 2007-08 game
