I'm building a new i7 system which I will use mainly for game but of course also, for a lot of other stuff here is what I had in mind:
CPU: i7 920
mobo: GA EX58 UD3R
GPU: saphire HD 5850
PSU: corsair 850tx
RAM: OCZ platinum 12800 (1600mghz and cl7)
HDD: Samsung 500GB F3
Optical drive: have plenty at home
CPU cooler: intel stock cooler
case: Haf 922
I'm planning on upgrading this system in the future : overclocking (with better cooler of course), second 5850 and maybe more. Since this is my first build I would like opinions on wether or not this would be a good build. Any advice is welcome =)
MadAdmiral thnx for the advice and yes my budget is round about that I can't say for sure since I live in Europe but it's around 1100euros. I've considered i5's but I want my system to last 5 or 6 years so then I want a really future proof system that's why I took the x58. Would the difference between a 5970 and a 5850 really ake such a difference in gaming performance because I have a 9800GT now and it handles most games on highest grafics pretty well. And I wuld do a lot of other stuff with my pc not just gaming. So if the difference in gaming performance is big between those cards then I'll consider the i5.
And coldsleep As I said before I live in Europe and here the 930 is about 40euros more than the 920 and that isn't worth it for me. If the price drops then I'd buy it. And I would like to play on highest resolution.
The difference between a 5970 and 5850 is huge. The 5970 (at stock) is two 5850s on one card. So it's basically Crossfire, though slightly better. Technically, the 5970 is two 5870 GPUs, so it can be massively overclocked. So you are essentially getting $800 worth of GPUs for $700.
To lay it out in more game appropriate terms, the 5850 can play most games with high details at 1900x resolution, with Crysis being the main exception. The 5870 (the one between the two) can play every current game at max details at 1900x resolutions. The 5970 will essentially max the FPS on every game out there. While Crysis isn't that important, it's a good indicator of what future games could demand from a GPU. You also need to keep in mind that once DirectX 11 comes into the mainstream, the FPS hit from using it will likely drop the 5850's performance into the unplayable regions.
I am of the opinion that by the time you need to upgrade the 5970, it will be time for an entirely new build. It will be sure to last long enough that technology will surpass it before it becomes too weak to play games.
We could give you a more specialized PC for your uses if you were to give us what you use it for, and about what percentage of time is spent on those tasks. If you game about 50% of the time and encode 50% of the time (for example), you would probably be better off with a different build than above.
The budget is more like 1300$ since parts are more expensive in Europe. But just to be clear here I would upgrade the 5850 to crossfire as soon as there is a need so I'm not planning to stay with just one. And the example you gave of 50/50 would be true in my case.
CPU: i7-920 232euros
Mobo: Asus P6X58D Premium 279 euros
RAM: G.Skill Pi Series 3x2 GB 1600 mhz CAS Latency 7 unavailable in europe but the one I mentioned is 160euros
HDD: Seagate 7200.12 500 GB 50euros
Case: HAF 922 90euros
GPU: HD 5870 400euros
PSU: Silverstone 750W 80+ Bronze 120euros
How much do we need to cut? If it's only a little, I would first look for a slightly cheaper PSU. That's really expensive over there. Check out the 750W units from Corsiar, SeaSonic, Antec or PC Power & Cooling. If you still need to cut some more costs, switch the board to a Gigabyte GA-X58A-UD3R. If it's more than that, there's some other changes we change make.
Mobo: Asus P7P55D-E Pro
RAM: 2x2 GB 1600 mhz CL 7 kit
These changes would keep the same gaming performance but drastically cut the price. In USD, it saves about $275...
If that's still not even close, you'll have to drop down to the HD 5850...
