I would ask what your main use was going to be for that machine and your overall budget because what you buy is very much down to what you need it for and are limited by.
Amd , or Intel doesn't really matter , per-say one has the well known brand comfort and bit more raw speed at the top end of the market , the other has a bit more of a kind upgrade path and excellent mid range price to performance ratio.
So if budget is strict , go for AMD , if its about getting the best processor and features go for an I7 with all the trimmings.
Compatability wise there is nothing wrong with that build but i would say the stock cooler will be a bit rubbish, So add a heat-sink and some thermal compound as well.
What ghnader mentioned " that the motherboard doesn't support SLI is true " So with that motherboard if you ever wanted to put more than one graphics card in you would have issues .
My reccomendation would be to get an ATI card as that motherboard will be able to use more than one of those due to it being crossfire ready but lacks the support for SLI .
Go for one of these instead http://www.ebuyer.com/product/266528
( that way if you need to you can add another graphics card at a later date in tandem)
I would want to know if you were really going to use all 8GB of that RAM , "
If you are gaming I'd bet not and then i would put more money into the power supply, and then add more ram a little later if needed .
If it was for video / image work then the build is very good the 6 core Thuban will be great for heavy multitasking , but wont give you much extra performance in games which have not been threaded to use much more than 2 or in some cases 4 cores unless you are willing to do plenty of manual tweaking in your system's processor affinity settings a heavy duty Quad core will do just as well.
it's not that bad, you need to relax if you haven't had one before.
I have that PSU now and I was going to keep it until I read a report and it showed better units.
but for almost 9 months it has been powering my main gaming unit.
so I do not recommend it to the OP but it isn't as bad as what you say.
and also calm down before you yell out recommendations on what someone should buy.
you need/should ask questions first..
usage, games, resolutions, money, location for availability of hardware.
your just accumulating points that have no substance.
dude, you need help.
what's the unit to be used for, gaming.? if so then what games at what resolution.?
then what's your budget for your hardware.?
One game I definitely want to be able to run is Starcraft 2 on high res. I looked at http://www.tomshardware.com/reviews/gaming-graphics-car... and the graphics card I have listed above is 1 tier above what is recommended. I was also thinking of Crysis. As for budget, I wouldn't want to go higher than $780 for hardware (excluding monitor). And yes, I thought it was obvious that I needed help. If I didn't, I wouldn't be here.
