Look at pinned thread with the following advice - right now your question has a lot of things missing in it. video editing? what kind? it would influence your storage requirement is you have to store TBs worth of data. Gaming - what kind? what would be your monitor? what is your budget? what is included in your budget? etc
PLEASE when you POST threads asking for input on system builds tell us...
1. What YOUR PC will be used for. That means what types of tasks you'll be performing.
2. What YOUR budget is. A price range is acceptable as long as it's not more than a 20% spread
3. What country YOU will be buying YOUR parts from.
4. IF you're buying parts OUTSIDE the US, please post a link to the vendor you'll be buying from.
We can't be expected to scour the internet on your behalf, chasing down deals in your specific country... Again, help us, help YOU.
5. IF YOU have a brand preference. That means, are you an Intel-Fanboy, AMD-Fanboy, ATI-Fanboy, nVidia-Fanboy, Seagate-Fanboy, WD-Fanboy, etc.
6. If YOU intend on using any of YOUR current parts, and if so, what those parts are.
7. IF YOU plan on overclocking or run the system at default speeds.
8. What resolution, not monitor size, will you be using?
9. WHEN do you plan to build it?
Note that it is usually not cost or time effective to choose your build more than a month before you actually plan to be using it.
10. Do you need to purchase any software to go with the system, such as Windows or Blu Ray playback software?
At the end of the day it's your money. There's only so much we can do
