Hi, I would like some comments on my build before I order.
 
 
CPU
Athlon64 X2 6400+, 3.2GHz, 2x1MB Cache, 0.09 Micron, Dual Core, Socket AM2, BOX
 
I would also like to know how much noise the cooler on this makes?
 
 
Mother board
Asus - M2N32-SLI/Deluxe, nVidia nForce590 SLI, Dual GLAN, 8 Channel Surround Audio, SATAII RAID, External SATA, SLI Dual PCI-Express VGA, DDR2-667/800, Socket AM2
 
 
Graphics card:
Inno3d - GeForce 8800GT, 512MB GDDR3, Dual DVI, TV-Out, HDTV, Passiv Cooling, PCI-Express, Retail
 
I've chosen the passiv cooled to reduce noise. I have one side open on my cabinet anyway, so airflow should not be a problem (right?)
 
 
Ram
2x Corsair - 2048 MB DDR2, PC6400, DDR800 - CM2X2048-6400C5
 
 
Harddisc
WD - 750 GB – SATAII-300 (Fluid) – 5400 - 7200 RPM / 16MB cache – WD Caviar GP (GreenPower) - Support Perpendicular Magnetic Recording
 
 
PSU
Xilence - Gaming Edition, 700W, Low-Noise, 13cm REDWING Fan, ca. 18dBa
 
 
DVD
Pioneer - DVR-215DBK, DVD±RWx20, DVD±R DLx10, SATA, Internal, Dual Layer, 2MB, SATA, Black, Bulk
 
I dont have a DVD writer, so though I'd buy one while I was at it
 
 
Operative system
Windows Vista Home Premium, 64 Bit, OEM - UK
 
 
Any advice will be highly appreciated  

Are you dead set on AMD?
 
Are you overclocking this pc?
 
What's the use of the pc?

I will primarily use it for gaming, and have no plans on over clocking my system, I might when it starts to get obsolete, but it's not a priority.
 
The reason I chose AMD was the price, since I'm very close to my budget maximum.
For the same price I can get a:
Core 2 Duo (Conroe) Model E6750 (2.667GHz), EM64T (Extended Memory Technology 64), 1333FSB, 4MB Cache (LGA775), BOX
 
or
 
Core 2 Duo (Wolfdale) Model E8200 (2.667GHz), Dual Core, EM64T, 1333FSB, 6MB Cache (LGA775), BOX
 
the E6850 or Q6600 is a bit more expensive. If there is a big performance difference I could go Intel though

All good choises aside from the gpu area and your MB.  
 
GPU:
Passive cooling the GT is a VERY bad idea. Its very unlikly the card will stay cool. Super bad chances even with high quality passive cooling. Its probably the hottest card on the shelf atm and makes heavy work out of even the best aftermarket cooling systems. You are much better off in that range of GPU going with the 3870 512 model card. They run cooler, are very vista friendly as they support dx10.1 and Nvidia does not atm, and OC a bit better then the GT can if you feel the need. The 3870 generics even run cooler and with less noise by a good bit out of the box. I recomend Asus as the brand for the best set of apps out of the box.  
 
MB:
Asus and Gigabyte have VERY well built, stable user friendly MBs atm. Go AM2+ socket 100%. AM2 is yesterday and will cut down upgrade options almost totaly. AM2+ will leave you open for plug in cpu upgrades for the next 4 years at least. The 790 chipsets perform VERY well. The xfire option is the best pcie-2.0 option statisticly by a good margin atm for multiple gpu upgradability atm.  
 
With the changes I listed above you will have a VERY solid upper mid ranged machine. It will game at 1680x1050 on a 22 inch in almost any title on pretty high detail with 2-4x aa and af. The only reason to go Intel with your setup would be for OCing ability. At the same time keep in mind that you will be spending more money on case and cooling. I dont see the point when you can just plant a new CPU in your rig next year or the year after. Your rig with the changes I listed above will perform just as good as the Intel options you listed. With your list and my changes you end up with a great gamer, best upgrade possibilities to be had hardware wise, much better dx10 performance with dx10.1 now and more to come over nvidia options and the most performance per$ for an upper mid ranged rig over the next 4 years. The Intel options is much more expensive as you will be replacing your MB and CPU and probably your ram as well by the time you need an upgrade along with a higher $ amount to start with.

Thanks for the quick replays.
 
I'm a bit lost in the motherboard area, but this is almost the same price as the one I chose, or is there a better choise?
 
Asus - M3A32-MVP/DELUXE, AMD 790FX, GLAN, 8 Channel Surround Audio, SATAII RAID, eSATA, Firewire, Quad PCI-Express VGA (ATI CrossFireX Support), Passive Cooled Northbridge, Dual Channel DDR2-800/1066, Socket AM2+ (Supports AM2)
 
As for the graphics card, I've seen the 8800GT beat 3870 in all the tests I've read. Will directX 10.1 make that a big difference in the future? I've always used Nvidia cards, but maybe the time has come to change?
 
However if I should go away from the passiv cooled one (and stay with 8800GT), my chose would be:
 
Asus - EN8800GT/G/HTDP/512M, GeForce 8800GT, 512MB GDDR3, Dual DVI, TV-Out, HDTV, HDCP Ready, PCI-Express, Retail
 
 
Any further comments and advice will still be highly appreciated

Agreed with what he said. I am flabbergasted every time I see a new build with an AM2 board. Well, what do I know? The average user thinks short-term. We know when the AM3 will hit the street. I wouldn't touch an AM2 board with a 10-foot pole. Maybe a 10.5-foot.

That's a good board, but maybe a bit of a splurge. MSI K9A2 Platinum overclocks the best, say most reviews.

AMD cut HD3000 prices and rumor has it that they will do it again. The 9800GX2 is overpriced, though it is priced lower by 10% now. If you must get nvidia, get at least the 8800GTS512

You can't crossfire nvidia. If you're getting an AMD build, might as well get ATI cards. They're cheaper. If you play Crysis and the like at 1080p/i, don't settle for anything less than HD3870X2.
