In other words, all your parts work together just fine
yes but there is more to it than just putting stuff together, some of his choices are unwise and can lead to trouble later on, like the ability to future upgrades, 2x 5770 are just a bad choice, the only way i would recommend that setup would be if you have already purchase a 5770 about 5months ago, have some xtra cash then by all means, but 2 at the beginning simply kill all upgrades path he could make ahead.
a i5 750 is a great processor, However in gaming a 955 and a i5 750 have around a 5% to 7% difference, depending on the game, but the 955 is also cheaper, the 890xx chipset is the most future proof board in the AMD family allowing him sata 6gbs and usb 3 and the addition of the 6 core support when release. and a 5870 will last you way more, at the resolution you intend to play you wont need to upgrade to a new video card, instead just get 2 more monitors and Experience the way its mean to be play!
So does that me that with that motherboard you are suggesting can you crossfire the Radeon HD 5870 with the Onboard Video Chipset the ATI Radeon HD 4290? Or do i just throw out the 4290?
The onboard video isn't a separate card, it's integrated into the motherboard. By choosing to get a gaming graphics card (or two), you are not going to use the onboard (except for diagnostic purposes if the discrete card fails).
also, SNAKEJ what is the difference between the RAM you suggested and mine... just curious.
there isn't a link to the ram u pick, so i don't know for sure which one is it.
but basically you want the lowest voltage with the lowest timing, lots of people like 1.65 with cas 7.
if you ever learn to overclock, you will see that lowest timing are just better as it allows you more room to go even higher, i wouldn't be surprise to see the ram i pick do 7-6-7-22 at 1.5, but since you don't know what overclocking is, i suggest you do research on it, when you get your pc just set the timings as per recommendation of the manufacture, until you learn what BIOS is and mess with it.
even though that has SATA 6gbs and usb 3.0 it still using an older chipset, the one im recommending is the new 890xx chipset, its the newest model from AMD, if you want something with no on board video ( which isnt a big deal) you need to wait till the end of this month and get the 890FX, however the price of the FX series is more premium oriented so I wouldn't be surprise if the price start at the $149.99 as entry and from there.
