I suspect you can save some money using some parts you already have, like your case and Windows XP.
Keep in mind that this build is geared specifically towards overclocking. It is OK if you don't want to, but if you read the article you can see what they do with it.

I would not recomment Quad-Core processor. Not much games (if any) actually needs it. Dual-Core is good too.

It good to know, what kind of monitor you have, if, for example, have some older model with 1280*1024 resolution (like me, btw), you don´t need newest graphic card, it´s overkill

For example, last month, I buy this (monitor is 1280*1024, as I said before):

Motherboard: ASUS P5QL Pro
Processor: Intel Core 2 Duo E7400 BOX
RAM: 2x 1GB
Graphics: Gainward 9600GT GS 512MB DDR3 9115
HDD: Western Digital Caviar SE16 3.5" 320GB WD3200AAKS
PSU: Fortron FX500-A 500W OEM

For the time being, every game, even new ones, like W40k: Dawn of War 2 runs on max details, with 4x AA.

If you're trying to get TF2 to work try running in DX 8.

TF2->Settings->launch properties

type "-dxlevel 80" without the "s

You will take a hit on graphics but this has let 2 people I know enjoy the awesomeness that is TF2.

i still think the problem is that you don't have a monitor

Thank you, i'll probably buy a new one right out, i found out somewhere here that buys used PC parts. I'll take a look at some of those parts and see which i can find at an acessible price here in Brazil

Also, i'll read about overclocking. If i am able to do it, why not? Sounds good

I run it on my 37" LG tv, the same i got my PS3 plugged into

Very good pc you have there. Do you believe mine only have 60gb HDD by now? Years ago i thought it was more than someone could need, nowadays i need to delete something to make room nearly every day. I need a big HDD, lol

Thanks, i'll try it later

Even so, the game takes like 10 minutes to load, but it sounds good as a temporary solution

I can close my eyes and use my imagination :D

Well guys, thank you for all the tips, i will buy a new pc. This one was the best on the market when i bought it, but it was in 1999 or 2000 lol, time to move on

My new guitar will have to wait xP

but imaginations don't usually have HDMI ports.

Upgrading this is hopeless you would need to look for long obsolete parts which can have rediculus prices at ebay compared to new stuff in shop.

Overclocking can get you better performance on cheaper parts. Just keep the following in mind:

It is very time consuming. Overclocking consists of changing settings a little bit at a time to see how far you can push the machine. Changing settings too far too fast can damage your processor or motherboard and cause you to have to replace them. If you overclock properly, you should not damage anything (though it has been known to happen.

Overclocking takes researching. You have to know things like when to increase the voltage running to your processor or graphics card.

Even if you overclock things perfectly, you are still reducing the lifetime of your parts.

He doesn't have a PCI-e slot nor an AMD CPU socket. 

Flow, time to build a new PC.
