If ur going for an AGP then u cld get the GeForce 6600 rather than one from the 5xxx series. It costs arnd 15-16k (cld be lower). If u want to spend a li'l less u cld always go for a 9800pro (arnd 13k methinx, and @
any rate better than
any 5xxx series card). But I'ld still recommend the 6600. (or the 6800nU, but it costs arnd 20K
)
I don't know why 2 modules cause sys hangups..but they're generally recommended as dual channel mode offers much faster mem access which the Athlon 64's mem controllers are fine-tuned (in a sense) to exploit.
Of course if u plan to add more mem in the future, ur probably better of with a single stick (as u'll have more free slots).
As regards cooling..stock cooling
should do..unless ur room is overly congested/airless/etc.etc. If u've enuf ventilation otherwise, and don't plan to overclock, I don't think u shld need anything extra.
Don't know much abt 939pin mobos available in India...plus have u thought about PCI-XPress support? Though it won't be a critical necessity,
maybe u cld wait for nForce4(with SLI
) mobos to become widely available in India. U cld check with ur dealer abt that.
