Since you guys recommended Assembling one, i guess i will

Are decent parts available here in doha ?? or would i need to import them from the US ??

Anyway I came up with while browsing amazon

VGA - EVGA GeForce GTX460 768MB

RAM - 2x2GB (or is 6 better?)

Motherboard - Asus M4A78T-E Socket AM3/AMD 790GX

CPU - Phenom II X4 965 Black AM3 3.4Ghz
http://www.amazon.com/Phenom-Black-3-4Ghz-512KB-4000MHZ/dp/B002SRQ214/re...

Case - http://www.amazon.com/Cooler-Master-RC-922M-KKN1-GP-Tower-Black/dp/B0026...

and a 750 GB HDD and a 550 watt PSU

So did i just screw up, or is this ok ??
