Are these parts compatible?

Well hi there, im planning on building my 1st gaming pc and im wondering if all these parts would work together.
Also for the Hardrive, im only using it for windows and programs, files are going to be stored on external hardrives. I would get a 40gb ssd from intel for windows, but i cant afford it yet.

So waddaya guys think? think this will all work together functionally and properly? gimme some suggestions

For gaming IMO this config would be better....with along with a faster graphics card and SSD - cheaper...

CPU + Mobo
i5 750 + Gigabyte P55A-UD3(A very good mobo with SATA 6GB/s and USB3.0, but doesnt support crossfire though)
For gaming the i7 9xx dont offer any significant performance in games and that too for a single card config, I dont think its sensible to go that route...

RAM + Graphics card
GSKillz 4GB DDR3 1600MHZ CAS7 + HD 5870 - As you will be going with single card, getting a powerful one would be a good option...

HDD config -
SSD + OS
OCZ Vertex 60GB + WIN 7 - Would suffice for OS and some games...

DATA - Samsung F3 500GB

DVD

CASE + PSU -
Antec 900 + Antec TP 550 - Has enough power to handle HD 5870 and an overclocked CPU

Cooler - Cheaper at amazon

Total - ~$1362 | $1332 Including rebates
And this PC will be an overall better gaming PC and with the SSD, far better in loading and booting....

^ Well if you are able to put it together, then you should know whether it would work or not right ?
My above post was just to suggest a better config based on your requirements...rather than spending money just based on the best and the costlier parts out there will not help overall...
For your question, Yes those will work together...

I wouldn't blow off gkay09's suggestions. His build would be much better for gaming.
