500$ish build~Need some suggestions

I haven't been to these neck of the woods in a long time, so i'm REALLY rusty on technology.

Last time i built a desktop was my p3 coppermine which i still use today, but the hard drive is failing, so i need a new computer

I plan on buying for around 500$, my budget allows up to around 650$ however. So i have expansion room.

I will use this desktop for basically light gaming (cs:source, games like that) photoshop, surfing the interwebz, and like, powerpoints and word docs. I'm not buying an operating system as i have a copy of XP professional, and i'm gonna wait till Windows 7.

Basically i want this computer to last as long as my p3 did, because my uses well, aren't demanding.

I came up with some parts i saw on newegg.com (all of which will be ordered from www.newegg.com)

I already have a monitor, keyboard, mouse, the peripherals, i need the core components and a case.

So here's what i came up with.
Note: I'm completely fine with Intel or AMD, whichever one will work.

Antec Three Hundred Black Steel ATX Mid Tower Computer Case - 60$

Western Digital Caviar Black WD6401AALS 640GB Hard Drive - 70$
http://www.newegg.com/Product/Prod [...] 6822136319

Need help with the hard drive... wasn't really sure, so i picked the one that had the most reviews. I would prefer a 320gb or a 250gb.... but i couldn't find any with similar performance (maybe i needed to look more in-depth) (preferable Hd's from WB or seagate)


CORSAIR CMPSU-450VX 450W Power Supply - 74$

SAMSUNG Black DVD Burner - 23$

LIAN LI 20-in-1 USB 2.0 Black Aluminum Card Reader - 23$

G.SKILL 4GB Dual Channel Kit Desktop Memory - 48$
http://www.newegg.com/Product/Prod [...] 6820231122

Basically i really need help picking between Intel and AMD

The CPU choices were:

AMD Athlon 64 X2 7750 Kuma 2.7GHz Dual-Core black edition Processor - 60$
http://www.newegg.com/Product/Prod [...] 6819103300

Intel Pentium E5200 Wolfdale 2.5GHz Dual-Core Processor - 70$
http://www.newegg.com/Product/Prod [...] 6819116072


Which ever one i chose, i would need a motherboard, and all the motherboards basically look the same with re branded companies on them. (i honestly don't understand motherboards )


What i put above adds up to 298$ without shipping and rebates. leaving basically 200-300$ for a cpu, motherboard, GPU, case fans, cpu cooler and games.

Case fans i'll be buying gelid or scythe for the quietness.

Your choices are all good. You may want more power if you want to do crossfire sometime in the future, but that 450VX is fine for 1 GPU. I would go with the e5200 out of those 2, it's a great overclocker. I have mine running at 3.33 Ghz on stock cooling. This should be a good board for it http://www.newegg.com/Product/Prod [...] 6813157143
This is a great GPU at a great price after a promo code http://www.newegg.com/Product/Prod [...] 6814102824 That should leave you some money for a CPU cooler, I don't know too much about those, sorry.
