E6850 is a 3GHz processor with 1033FSB. it's a nice processor but you can get a Q6600 quad core (2.40Ghz) by paying a 1K RS difference in pakistan. anyway still I say that remain stick with E6850. For Ram, get the crosair 800Mhz (I personally using Kingston though).Sure, nothing has changed from the above pretty much.
Intel C2D E6850 - 2.66Ghz
GA-P35-DS3R Motherboard
20" LCD
2Gigs of RAM @ 800Mhz - No spcific model in mind just yet.
PSU - 500Watts
250GB HDD
GPU - 7200
For GPU, why you are buying that old one? why not the 8-series? due to budget? if you are short @ budget then lower down the CPU and get the better GPU..
