Currently I am creating a new low-budget desktop that will hopefully run WoW/CS:S/CoD3 on from Newegg.com.

The processor i'm looking at right now is a Intel Pentium E2160 Allendale 1.8GHz LGA 775 65W Dual-Core Processor Model BX80557E2160 right now on sale for $82, customer reviews report OC'ing it to 3GHz no problems keeping it cool. (http://www.newegg.com/Product/Product.aspx?Item=N82E16819116036)

The video card i'm looking at is SAPPHIRE 194L Radeon X1650 256MB 128-bit GDDR2 PCI Express x16 CrossFire Supported Video Card, though its only 8 piplines and 128-bit, customer reviews report great frame rates in WoW and some DX10 games. On Newegg for $53.99. (http://www.newegg.com/Product/Product.aspx?Item=N82E16814102035)

Currently theres a special on memory at newegg, Kingston 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 667 (PC2 5300) Dual Channel Kit Desktop Memory, running for $38!! It's Kingston need I say more? (http://www.newegg.com/Product/Product.aspx?Item=N82E16820134384)

And for the mother chip, I'm looking at the EVGA 112-CK-NF72-K1 LGA 775 NVIDIA nForce e-7050/610i Micro ATX Intel Motherboard, supports the dual core processor and has some pretty good customer reviews. Does not support Crossfire but I play to use only 1 vidcard. Was $64. (http://www.newegg.com/Product/Product.aspx?Item=N82E16813188023)

And finally to give juice to all the components I chose the XCLIO GOODPOWER 500W ATX 500W Power Supply, I've heard great things about Xclio so i'm going to give them a try. Cost about $49. (http://www.newegg.com/Product/Product.aspx?Item=N82E16817189005)

I already have the case that supports mATX form factor and 2xSeagate Barracuda 7200.10 ST3160815AS 160GB 7200 RPM SATA 3.0GB/s Hard Drive's ready to be raided to 0, for ultra performance. Each were $52. (Newegg's Link)

So all-in-all I invested about $300 and some spare pieces I had laying around into a pretty decent wow playing machine. Newegg estimates the delivery should be here in about 5 days, if anyone has any comments or has any proposable flaws please don't hesitate to post! 

Yup, one of the main reasons I chose this processor was for the OC'ing ability, 2 cores running at 3GHz with stock cooling is going to be nice. 

Although on Tom's Hardware they report getting up to 3.2GHz with standard cooling, but 2 GB's of ram (without heat spreaders) and standard cooling and a moderately hot video card I plan on OC'ing it to a mere 3GHz.

Edit:
I might have to invest in a PCI Fan to direct hot air off of the X1650 though.

And Coknuck what do you think about the 500W PSU, do you think that will be enough juice? CPU reports 65 watt usage like normal CPU's but its dual core and its going to have 2 HDD's and the X1650 & 24pin MOBO, it should be enough but i'm looking for others opinions.

they dont have mine on newegg anymore (but i ordered it from them) and its a Hipro 500 watt with 18amps per rail i think. and it runs my 24pin motherboard, geforce 7950gt graphics card and two dvd drives, a amd athlon 64 x2 dual core 5600+ cpu, and a 120GB sata harddrive. i think you should be fine...
