Aha
Intel graphics- there lies ya problem
even iof you finally force the game to run it will be slow and will look horrible.
get yourself a good nvidia or ati, at the very least something that supports directx 8.1
any ATI radeon higher than 9000 or any nvidia geforce higher than geforce3 should be ok (except geforce 4MX)
prices vary greatly. hit ikeja and look around. some geforce 9550s and 9200s doing the rounds there.
yes, the gaming section is boring- because the gaming scene is boring at the moment. Its the 'pre-summer calm' period

when halo3, dmc4, mgs4, gta4,killzone and all the other crazy games we have been promised over the past few years start appearing, the thing may get jazzed up again.
