I have dedicated the past 2 months of my life to finding the best posible configuration while not going overboard price-wise(because Im giving from my own limited pocket).
What I have come up with is this:

MoBo -P5N-D ASUS NForce 750i SLI 2xPCIe 2.0 4xDDR2 800MHz
CPU - Intel Q9300 2.5 GHz
Memory - Kingmax DDR2/800mhz 2048MB PC6400 FBGA Mars(I'll add in some more RAM during the next 2 months)
GPU - Zotac 9800 GTX(if I win the competition tommorrow) 512 DDR3 OR
Palit 9600 GT 1GB GDDR3 Sonic
HDD - SAMSUNG 200GB SATA, 7200rpm, 8MB NCQ SpinPoint S250 Series
Case & PSU - SUPER MiddleTower ATX w/PREMIER PS 500W
I'm still deciding on the CPU cooler..

So what do you guys think? what can be changed/added while keeping it in approximatley in the same price range(However I will consider any suggestion no matter the cost of implementing it. At least for future purchases)
