$2300 gaming PC

*Sorry for he double post, but because the system does not seem to recognize the euro symbol, the original thread appears without a title and the system denies me the right to edit or delete the original message*

Hello.

This would be my first attempt at building a PC from scratch and I'm a little anxious. I have thought of the following configuration and would like your advice on it. I'm really an enthusiastic newbie when it comes to hardware, so I'd prefer if things were relatively simple to assemble. I thought I'd also give a try at overclocking, since moderately overclocking the i7 920 seems easy enough for dummies.

Anyway, here are the details.

APPROXIMATE PURCHASE DATE: next week
BUDGET RANGE: about €1600 (that is around $2300)

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: gaming, Internet, ...

PARTS NOT REQUIRED: keyboard, mouse, speakers, monitor
PREFERRED WEBSITE(S) FOR PARTS: LDLC.BE, but I use here links to newegg, because it's in english)
COUNTRY OF ORIGIN: Belgium (so English is not my fiirst laguage, sorry)

PARTS PREFERENCES: Intel, rest is more or less open

OVERCLOCKING: Yes (moderately, to about 3.33)
SLI OR CROSSFIRE: Not right now, but want possibility for crossfire later

MONITOR RESOLUTION: 1680*1050, with probable increase next year with new monitor

Main questions:
* I'd like to moderately overclock the i7-920, to about 3.33GHz. Is the stock cooler good enough in this configuration or do I need a more specific cooler. If so, which one do you suggest ?
* I really have no idea about a good PSU
* I'm open to any alternative in the same range of budget.

Thanks in advance to anyone who is kind enough to give a look at this.

Looking forward to reading you,

I second Why-ME on the Corsair TX850, or maybe even the 1000ATX, with 1000W of continues power. If you think thats too much power, think again. With the 5870 you be running and the 920 OC to 3.3+ with a massive cooler mounted on top, this is a good start. Not to forget that you may want a second 5870 in the future to run crossfire, which makes this PSU minimum. Always think ahead, it saves you money in the long run. By the way, the stock PSU isn't going to get you anywhere close to 3.3+. If you want to run air, I have a Thermaltake Spin-Q that performs almost like a liquid cooling system. Massive cooler, so it dispence a lot of heat. Excelent for OC. As low as ram is getting these days, invest your money on 6G @1600. They will perform better. Just like Why-ME reccomended also, good thermal comound is vital for new built projects. Invest in it. Let me know if you have any questions. Good luck.
p.s. The 5870 will sweep the floor with any other single cards out there. It almost competes with my GTX295, and thats a duel card. Good choice and big bang for the bucks. Get two of these in crossfire sometimes in the future and you have it made.

Sounds good. You know what, you are right. At this entry level, the 1600 would be not a good choice. I have 6G @ 1067 with my 920 and that performs impressively. The 1333 is an excellent, if not, the best option here for you. I am glade I was somewhat of a help. Sorry if I missed out, but are you going with the 5870, as recommended a few times, for your built? Let me know...

Drop the caviar greens for caviar blacks or samsung spinpoints, either will run significantly faster.
