CPU: Intel Core i7 930 (2.8GHz)
Graphics: nvidia GeForce GTX 470
Memory: OCZ DDR3 3x 2GB 3-channel
HDD: WD Caviar Black 1TB SATA III
I would like to know:
Which component is mostly likely to be a bottleneck?
Which motherboard would support all those above?
How many power would I need?
Is air cooling system enough? (May do a bit overclocking)
I really would appreciate any sugestions or comments. Thanks.
Ok well I would answer your questions however I find your build could be improved by going with "some" different parts... Lets see what we can do:
The i7 930 is not barely ever required for gaming, only when running two or more high end graphics cards such as 5870s. Considering this you can pick between a P55 or an AM3 build. These would save you a lot on the processor which would allow you to spend more on the graphics cards.
I don't think you are able to edge up to the $700 5970 though. If going with this card then you may think of XFiring it later in which case a 790FX motherboard may be recommended to enable 16/16 XFire.
