Hello! I will be building a PC from scratch for the first time ever and I want to able to run all the current games at high settings.

Here is my build so far:

Motherboard:  Asus P7P55 Deluxe Motherboard - LGA1156, Intel P55, ATX, Dual-Channel DDR3, Intel DMI, SLI, CrossFireX 
Processor: Intel Core i7 860 Processor - 2.80GHz, LGA 1156, 8MB L3 Cache, Quad-Core, Lynnfield, Retail 
Memory: Corsair XMS3 Tri Channel 6GB PC12800 DDR3 Memory - 1600MHz, 6144MB (3 x 2048) 
Hard Drive: Seagate ST31000528AS Barracuda 7200.12 Hard Drive - 1TB, 7200 rpm, 32MB, SATA-3G 
Power Supply: C13-2503 :: Corsair TX750W 750-Watt Power Supply - ATX, 140mm Fan, SLI-Ready, SATA-Ready, 80Plus
Video Card: Zotac GeForce GTX 275 Video Card - 896MB, PCI Express 2.0 x16, SLI Ready, (dual Link) Dual DVI
Operating System: Windows 7 64-bit

What do you guys think? Will I be able to run high settings? I haven't decided about the cooling system yet.     
 
Any suggestion will be nice!! =D

You don't need a Crossfire mobo unless you're planning on getting 2 ATI cards in the future.  Your Nvidia card won't benefit.  edit - oh I see it has SLI and crossfire.  Still probably spending more than you have to there...
 
Personally I'd get EVGA if you want a Nvidia card and I'd get a Western Digital HDD over Seagate.

What would be a good mobo for this build? I'm a total noob when it comes to this stuff...

That board is also SLI so he's good. Agreed on EVGA for the GPU, they've got the best customer service and also on the Western Digital. Try the WD Caviar Black 1TB.

Thanks for the suggestions!! 
 
What's a good EVGA card under $300? 
 
The highest resolution that can run the GTX 275 is  2500 X 1600. 

Make sure you watch Brad's video...it gives good advise.

LOL, yeah Brad's video is extremely helpful!! =p 
 
Ok how about this card:   EVGA GeForce GTX 275 Video Card - 1792MB, PCI Express 2.0 x16, SLI Ready, (dual link) Dual DVI, HDTV, HDMI (w/ Adapter)

" Make sure you watch Brad's video...it gives good advise. "

At this point in time, you shouldn't be getting an Nvidia Card. Ati's 5870 is the best bang for buck at the moment, and will be able to play all games at highest res with highest settings and maxed AA and AF. It also of course has DirectX11, which will provide tesselation in future games. From there you can then simply buy more 5870's for crossfire in the future when you need to upgrade. The other option is to wait for Nvidia's next line up, which is rumored to be significantly better than ATI this gen, but that could be at least 6 months away. 

On a serious note, why not get a cheap card now and wait for the epic Nvidia card coming out early 2010?

Hmm...the 5870 is $400 which is bit over my budget.  
 
What would be a good cheap video card that can run games on high?

I've been a console player all of my life and this is the first gaming rig that I will build.  
 
Which one is better? ATI or Nvidia?

I am definitely going to make two changes to my list: I will be going for the 1 TB Western Digital Black Caviar and the EVGA GTX275. 
 
I honestly don't have a high end monitor right now. All I have is a 32" Samsung that can only run up to 720p but I'm building this PC right now so that I don't have to upgrade for the next couple of years. You could argue that with a 720p LCD TV there's no need for all this high end stuff but I may buy a 1080p monitor sometime next year. As far as games go, I am really into Left 4 Dead on the PC and i'm kind of tired of having to play it on laptop at the lowest settings possible. 
 
What do you guys think?  

I say buy a 8800 or a 9800, and save the money you save on the card for the new card in 2010....the next gen cards are going to be a HUGE leap.  Trust me man, don't buy a card during a transition period.

That ram won't work with that motherboard. You have to get Dual Channel ram for socket 1156 boards. Check out the Tech Report its a great site if you have any computer questions. They have a system building guide that should help you out and great people in the forums. 
    

Don't forget to get a mobo that supports DDR3 RAM, don't fuck yourself in the ass by getting a DDR2 mobo.

Moving this to the PC forum.

" @KaosAngel: Can you please direct me to a good 9800 card? "

 Flat out wrong. Buying the top of the line, flagship model is in NO WAY the best value. You pay a large price premium for getting that technology first (which will not be used in any major way for another several years).  The best value right now is unquestionably the 4870 (1gb). TWO of those cards in Crossfire would still cost about a hundred dollars less than a single 5870, and the performance benefit between a single card of each is minimal. "

A single 5870 costs about $100 more than 2 4870 in CF, you're right, but a 5870 also has DX11 and future scalability. The performance benefit over a single 4870 is also not minimal, especially if the OP wishes to run in max graphics  http://www.tomshardware.com/reviews/radeon-hd-5870,2422.html. If he gets 4870 CF now, not only will he not have DX11 access (which, since it's out already is probably a good idea to get if you're buying a new comp to save you the hassle in the near future), but it will be harder for him to scale in the future, as an additional 4870 would not significantly help performance. Whereas if he gets a 5870, purchasing another 5870 to CF in the future will give him a much more significant performance boost, thus being the best bang for the buck long term.  "

I have noticed a trend in PC game development. Since Crysis, it doesn't seem developers are keen on pushing the hardware envelope so much. They seem to have relaxed a bit. From the looks of your build, you should be able to max almost any current or upcoming PC game for the next couple of years. The flipside of that coin is that you could spend much less, upgrade a bit more frequently, and still achieve great performance if this game continues. I just noted in the Dragon Age forums that I am running that game in 1080p with all settings on high (except AA) on a very modest build. I have myself been in your shoes wanting to max everything and have the best possible build, but there is another way to still have fun and save some cash. Just throwing that out there.

Fans. More fans the better.

Also, enjoy your immediate obsolescence. The i9 chips are already in pre-production, and are over 50% faster than i7.

Enjoy your 700€ pricetag. "

Don't know if this build was ever done but first off;
1. 1366 Motherboard, the 1156 is a more consumer grade i5/i7.
2. if you made the switch to a 1366 X58 Motherboard, i7 920
3. 1TB drive for your OS is dumb. You will most likely not fill that drive with Apps and Games and you wouldn't want to; get a smaller Operating System drive i'd say the 640WD Black and then get the 1TB WD Black for your storage of movies, music, whatever.
4. You will most likely never exceed 1920x1200 so your resolution doesn't matter unless you spend the money on a 30" display.
 
lastly if you bought a 1366 Mobo you'd want to go triple channel RAM so 3, 6, 9 or 12 gigs of RAM with a triple channel kit. the 1156 only supports dual channel.

" @torus: I'd argue that it makes more sense to stay just behind the bleeding edge with PC hardware.   As long as you keep on top of upgrade cycles your fine. Even if you don't it still makes sense. I bought my q6600 system just as they were starting to tail off, right before the 45nm cores came out, its held me in good stead so far and I also went for a 275, my system is still doing well. Sure it doesn't have DX 11 for the moment but crysis flies and anything DX10 can be run full whack,   Also if the OP keeps waiting for the next new chip/card to come out he'll never build a PC...  Jus' sayin'... "

I believe that buying current hardware is not a logical decision, if one is concerned with cost. Especially right before the new version comes out (when the new one comes out, current hardware will drop in price.) "

PC is a waste of money. Mine is awesome, spent lots of money building it up but there are no games!!! none of my genre anyway. 
Good luck on the build however!

Oh wow, they put both SLI and Crossfire on the same mobo now-a-days?  Interesting.
