First Gaming Rig - Looking for Advice

[mdt0310]

Hey, all. I'm planning components for my first homebuilt rig and I would like some feedback.

My primary curiosity is about the Power Supply. I'm currently looking at a 750w PSU, but wondering if I could step down and save some money if that is ridiculously over my needs.

I'm trying to keep my total budget, including all the peripherals and bells and whistles, in the 1500-2000 range, and right now i'm coming in just shy of 1800.

Thanks for any wisdom you may be able to impart! I fully concede I'm pretty new at all this.

The first thing I noticed was that your hard drives are SATA interface and your optical drives are IDE. SATA would be a better way to go.

This might be a better choice of ram for you too. (I'm partial to G.Skill)
This gives you 4gb of ram http://www.newegg.com/Product/Product.aspx?Item=N82E16820231189 , or you can double that for 8gb. If your primary use is for gaming and the usual computer stuff, then 4gb is plenty.

If you need to trim back some to get more in line with your budget, you could do without the sound card. On board sound works very well, and if you're like most gamers, you'll probably use a headset anyway. You could also save some money by going with Vista Home Premium instead of Ultimate. The only real benefit of Ultimate is having remote access to you pc. Plus, you picked the Retail version instead of the System Builders version.
This comes with a free upgrade to Windows 7 too. http://www.newegg.com/Product/Product.aspx?Item=N82E16832116677

Otherwise, it's a killer setup.

What do you think of that?

Apart from what RickyTick said, the 650W version would do easily (even the 550W would without any problems, but for some reason it's the same price as the 650W). http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005
Also, with your budget, I would stay with the OCZ memory you linked. It's some of the fastest memory there is atm, and I don't think the $30 is worth the change.

[RickyTick]

Thas makes good points. However, the 750 watt is only $10 more than the 650 watt, so it seems like a better option for the longevity of the pc.

I also didn't think it would be a great idea to run triple channel ram on a motherboard that only supports dual channel. I could be wrong on that, idk.
