This will be first PC build (if everything is in order :S) and I am curious to know if all of the components I have picked will run smoothly together, if at all, or if I will need any additional parts.
I would appreciate any - any comments. Thanks.
According to this review: http://www.techpowerup.com/reviews/ATI/Radeon_HD_5870/7..., no, altho that is with 4x AA, so maybe if you turn AA down it might. If any card can get that high it would have to be the ridiculously expensive 5970. Which is unnecessary to buy for 2 reasons, the first being price, the second being that you can put more than one graphics card onto that mobo. And 750W from Corsair will be able to handle it.
Everything is in order, altho I wonder why you're getting that 160GB Seagate 7200.11, which is from a 'bad' generation of Seagate drives.
And I think you would need to buy another SATA cable to get 2 HDDs and a DVD drive connected.
The motherboard will have onboard sound and network, so you don't strictly need either of those cards, maybe you have a specific reason for buying them, in which case, fair enough.
