Hi, im planning on building my own pc and have come up with a spec, as this is my first time build i was hoping someone with a little more experience would be able to tell me if the configiration would work... like the graphics card fitting the motherboard etc.
here is the list of components accompanyied with accompanied with a link to where i plan on buying from.
Get the F3 over the F2 Ecogreen, it will be a lot faster even though it is slightly smaller. The 1TB F3 is one of the fastest HDDs available, the F2 is a green version so they severely reduced the speed to save power and reduce noise. http://www.ebuyer.com/product/205028
You definitely need to get a higher quality PSU, that arctic power PSU is rated for 700W but only has one PCI-E connector, sounds awfully weak to me. The 650TX will have plenty of power for 2 5770s but costs significantly more but thats the price of having a decent PSU. http://www.ebuyer.com/product/135514
If you only plan to run a single 5770 you can get by with an EA500 http://www.ebuyer.com/product/120377
I would not recommend using a 'green' drive as a boot drive, as it will be very slow and they don't use a significantly less amount of power compared to performance drives, which don't use that much power anyway. So I think you should change the drive to this: Samsung Spinpoint F3 1TB.
For a purely gaming build at that budget, you would be better off going with an i5-750 and a P55 motherboard or an AMD Phenom II X4 955 and an AM3 motherboard, and using the savings from CPU/Mobo/RAM on a bigger graphics card.
If you're trying to build a number-crunching machine that can double as a lower-end gaming machine and HTPC, then you might consider spending just a little more to get the i7-930, and follow the rest of Silvune's suggestions.
If you could fill out the new build form linked in my signature, more detailed advice can be provided.
