First build, compatibility reviews requested

I'm guessing you're in England correct?

If so I don't know what components are available power wise, but check out the Corsair Builder Series, it's the only brand of PSU that I really use and recommend. They're nice, solid, well constructed and stable.

I have that same motherboard and it's great. I've never had any issues with it. But if you really want a better CPU the X6 1055T isn't that much more than the X4. The bad thing about AMD ones is that it make take one or two tries before you get one that's good and stable. I had Gigabyte and MSI boards that I tried that failed on me almost immediately.

That Seagate HD is pretty cheap, get a second one if you can and hook it up through RAID 0.

If you can get a good after market fan, do so even if you don't really plan to overclock. Most of the CPU fans that are included with systems are junk to begin with. If you want an inexpensive one, the Cooler Master Hyper 212 is excellent.

As far as video goes check out the 6790, it's a much more recent card than the 5770, and has AMD's excellent Eyefinity technology that will allow you to hook up multiple monitors very easily.

Thanks a lot for you're suggestions, i'll have a look at the cooler master, graphics card and psu, but i dont really have to much money to spare for another hard drive and cpu, i'll stick to external hard drives if i go over the 500gb  

External HDs certainly not a bad way to go.

So i'm making changes to the graphics card and psu.

Graphics card- ASUS HD 6850 Direct CU 1GB GDDR5 Dual DVI HDMI Display Port Out Graphics Card

CPU- Corsair 600W CX Series V2 PSU - 6x SATA 2x PCI-E

And i plan to fill the two 80mm fan slots with two of these- 80mm Zalman ZM-F1+ (plus) Quiet Case Fan Speed Adjustable

The 6800 is a good choice, I've bought a few of those cards for work.

Ah right, thanks again for all the help, will i have any compatibility problems with my current selection?

Everything will be compatable in that list. I use a 6850 and it is a good graphics card for the price. My recomedation would be to spend a little more on your CPU as that will probably be the botleneck with your build
