Can ur board support PCI-e?

ATI or nvidia fan? Based on 22" monitor below.

Mainstream:
Nvidia GTS250, GTS260
ATi 4870 512MB

Entry:
Nvidia 9600GT,9800GT
ATi 4850.

Get the non ref ones. Run cooler. 4850/4870 PCS or HIS if u willin to pay a lil more. PCS is a lil cheaper. $169 for Ati 4870 PCS, last i heard a mth back.

GTS250, get the Asus dark knight one. $200+

4870 performs better den 260. In fact in the whole lot, 4870 is my recommendation. 4850 i thk its about $20 bucks cheaper.
Hope that answers your GFX question.

PSU: Get anything from 500w onwards. Andyson is a good budget brand. Coolermaster Realpower 550w onwards. OCZ/Corsair for better ones.

Shops I dont know, maybe someone else can advice u here.

There you go,
hope u enjoy ur upgrade.
