Hi all :hello:  ! New to the forums here, I've come up with a new build and was hoping to get some opinions on it.
I already have a Antec Skeleton (Case), CD/DVDRW drive and 4x500GB 7200rpm hdd's which I am planning to put into a RAID5.

AMD Phenom II X4 Quad Core 965 Black Edition 3.40 Ghz
http://www.overclockers.co.uk/showproduct.php?prodid=CP...

Asus M4A79XTD Evo (Socket AM3) DDR3 Motherboard
http://www.overclockers.co.uk/showproduct.php?prodid=MB...

Patriot Sector 5 Viper II 4GB (2x2GB) 1600MHz Dual Channel + 3D Mark Vantage RAM
http://www.overclockers.co.uk/showproduct.php?prodid=MY...

Corsair TX 850W ATX SLI Compliant Powersupply
http://www.overclockers.co.uk/showproduct.php?prodid=CA...

XFX ATI Radeon HD 4890 1024MB GDDR5 PCI-Express Graphics Card
http://www.overclockers.co.uk/showproduct.php?prodid=GX...

I am planning on buying two HD 4890's and putting them into crossfire, I chose these cards because they are high end dx10 cards and are alot more powerfuller than the dx11 5770's that are the same price.
Reason for the CPU is that it is currently AMD's fastest quad core, and not as pricey as the i7. No specific reason for the motherboard apart from it does what I require it to do (2 x16 2.0PCIe slots and 5xSATA; also I'm not a major fan of Gigabyte mobo's =/). The RAM simply because it's cheap, 1600MHz and had a reasonable low latency from what I could tell :S? I'm hoping 850w psu will be enough for what i have also?
my preferred buyer is www.overclockers.co.uk or www.ebuyer.com, but I don't mind buying from anywhere else in UK/Ireland as long as the delivery isn't too expensive :D 
the total price is £683.69 inc VAT, I'll be happy to go slightly up in price if someone has any better builds to offer or any critisism?

OH, one other thing, I doubt I'll need to but I don't plan on overclocking to prevent a lack of lifespan in the components =/?

Thanks :D

Sounds like you've read enough benchmarks to come to the conclusion. I don't disagree with that.

No, AMD isn't the fastest. Word it careful. This is an Intel-loving forum (even I run Intel, I recommend AMD where budget is limited). Anything that semi-praises AMD would call for flame throwers. :D  AMD is the most affordable quad core, but their x4 cpus are generally more power hungry. Look at the TDP.

125W for 956 vs 95W for 750

500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)

At a minimum for HD 4890 CF, a 600W PSU is required. If you want to save electricity, get a bigger PSU so that it won't be stressed out under load.

So far so good your specs are.

I meant that the AMD 965 Black Edition 3.40 was currently AMD's fastest quad core, not the fastest quad core out of intel and AMD :p  but I can understand that Intel are currently raping AMD (but ATI > nVidia imo ;) )

So you reccomend an even higher wattage PSU? (also how will getting a bigger psu save me electricity if it draws more amps? :S)

I wouldn't say Intel is raping AMD. Intel owns the high end budget, AMD owns the mid and low end budgets...

And it's not just your opinion that ATI is better than nVidia right now. Its a fact.

A higher wattage PSU will save you money because the wattage quoted isn't how much it always draws, its just the maximum it could. The reason it would save you money is that PSUs are more efficient the closer you get to a 50% load. Too high or too low will be less efficient.

For example, an 80+ Bronze Certified PSU is 82% efficient at 20% and 100% load, while it's 85% at 50%. So if you get a bigger PSU that is at 50% load when supplying 500W while the smaller one is at 100% for 500W, the bigger unit will only require 588W from the wall. The smaller one requires 610W.

In addition, bigger PSUs are typically more efficient. You rarely see a PSU with under 600W at the higher 80+ levels (Silver and Gold), and only a few are 80+ Bronze or 80+. Once you get above a certain level, almost every unit is at least 80+, many are 80+ Bronze and a few are 80+ Silver or Gold.

What he said.

It's up to you if you care about electricity more than anything else or not. IMO, a clean power source is the most important in computing. I used to have a UPS. When power goes out for a few secs, I get a blank screen and lose everything I am doing.
